摘要： The current draw of a wireless device, e.g., a cordless telephone, is minimized for a cradled remote handset drawing power from an AC outlet. This allows a greater portion of the total current amperage provided by the AC to DC converter to be allowed to charge the battery in the remote unit, and reduces the overall maximum or peak value of the current draw of the wireless device. With an improved peak power budget, a smaller (and presumably less expensive) AC to DC adapter than otherwise necessary may be used to power the wireless device. In one aspect, sniff operations of the remote handset are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit, e.g., receiving a quick charge or trickle charge to its battery. In a second aspect, sniff operations of the base unit are disabled or otherwise suppressed while the remote handset is in the cradle of the base unit. In a last aspect, the charging mode of the battery in the remote handset of a wireless device changes based on activity in the remote handset.

摘要： Apparatus and method to minimize power usage by electronic devices. In a particular disclosed example, the battery power of a remote handset is reduced by extending the sniff period of a cordless telephone when the remote handset is remote from its base unit and the user is not likely to use the cordless telephone (e.g., when away from the house or when asleep). A low power mode module causes the electronic device, e.g., the remote handset of a cordless telephone, to remain in an extended low power STANDBY mode, or to extends the period of the periodic transition to a receive only STANDBY mode to check status registers at the base unit, at appropriate times. In one embodiment, a low power mode table contains entries defining periods of time during which the remote handset may transition between the low power STANDBY mode and the receive only STANDBY mode. The remote handset transitions to a fully powered transmit/receive (TDD) ON mode, e.g., in response to an appropriate status condition, or in response to the activation of a particular button or sequence of buttons at the remote handset. The extended STANDBY mode may alternatively be activated in response to input from an external device such as a home security system indicating that the user of the cordless telephone is not willing or able to answering any incoming telephone calls. The extended STANDBY mode may also be entered upon determination by the cordless telephone that the telephone line is already in use by another extension (thereby rendering unlikely any receipt of a ring signal condition from the base unit).

摘要： A method and apparatus to perform a real-time drift correction of a remote handset's local oscillator in a digital cordless telephone. The remote handset begins in a standby (sniff) mode. The remote handset periodically wakes from a sleep mode and goes into a normal link verification mode. Once in the link verification mode, the remote handset enters a time division duplexing (TDD) mode and attempts to establish a link with a base unit based on the timing of the TDD data frame. After the remote handset establishes a link with the base unit, the remote handset requests a security word from the base unit. Upon receiving the requested security word, the remote handset determines if the requested security word matches a security word of the remote handset. The remote handset implements a software frequency adjustment of its local oscillator. Once per frame, the remote handset enters a timing recovery state where the current state of the frame is compared with a previous state. When the cumulative timing slip is greater than a designated threshold, a frequency adjustment is made. During this exchange of commands between the remote handset and base unit, the remote handset continuously adjusts its local oscillator to achieve frequency alignment within, e.g., 1 part per million (ppm). Alternatively, frequency alignment may be achieved to a specified value. The period of the frequency alignment can be lengthened (or even suspended) during certain power critical modes to reduce power consumption. For example, the period of the link verify operations (and thus the frequency alignment) can be lengthened or suspended when the remote handset is being quick charged. Moreover, the period of the link verify operations can be adjusted based on a voltage level of the battery in the remote handset.

摘要： Apparatus and methods for adaptively, reliably, and accurately measuring the duration of an alerting or other signaling tone. A tone detector in accordance with the principles of the present invention accurately measures a duration of a tone burst (i.e., tone pulse) using a long frame length DFT and a short frame length DFT. Based on information obtained by the short frame length DFT, the long (i.e., standard) frame length DFT may be interrupted and reset to begin a new frame of data synchronized with the start of the next short frame corresponding to the processing by the short frame length DFT to minimize noise in the processing by the long frame length DFT and to greatly improve the resolution of the measurement of the duration of a particular tone to correspond to the lengths of the short frames used by the short frame length DFT. If desired, after a tone is initially detected, the frame length of the short frame length DFT can be iteratively reduced to increase a resolution of the measurement of a tone start time and a tone end time used to determine the duration of the detected tone burst.

摘要： A call related information detector/receiver system which is capable of downloading call related information received at that device to another call related information detector/receiver system remote from the system which initially received the call related information, back over the telephone line. Thus, a remote user while away from the home or office can receive and synchronize call related information at a system other than the one which initially received the call related information. Thus, a remote user can update a local call related information system and review past callers to their home or business telephone at their leisure. Upon establishment of a telephone call between customer premises equipment respectively associated with the two relevant call related information detector/receiver systems, a remote call related information system will request download of call related information logged from another call related information system using the established telephone call. In the disclosed embodiment, the request signals are encoded with DTMF tones, which the receiving call related information system monitors for. Upon acceptance of a request to transmit logged call related information, previously logged call related information is retrieved from its log, formatted for transmission together with suitable header information such as the identity of the transmitting call related information system, and FSK modulated for transmission back over the telephone line. Preferably, the speaker or earpiece of off-hook customer premises equipment will be muted or suppressed during transmission of the data corresponding to the call related information. The particular call related information transmitted may be particularly or generally requested by the remote call related information system, either by pre-stored commands based on a power up configuration of the requesting call related information system, and/or in response to a direct command input by the remote user using DTMF tones.

摘要： An on-hook EOH indicating telephone includes a parallel set detector, an EOH signal detector, and an indication module to activate a configurable audible and/or visual alert indicating that another telephone is off-hook and should be hung up. The audible alert may be a unique ringing of the otherwise conventional ringer (e.g., every 5 minutes, at a unique cadence or frequency, etc.), or may be an audible tone output from the speaker of the on-hook EOH indicating telephone. The visible alert may be, e.g., a text message on a display of the on-hook EOH indicating telephone, a blinking, flashing, etc. of an LED, or other visible attention getting technique. When the central office presents the extended off-hook (EOH) notification signal to the desired telephone line, the invention-equipped telephone detects a parallel set in use, and then listens for the EOH signal. Upon receiving the EOH signal, the inventionequipped telephone will uniquely ring, visibly illuminate, flash, or otherwise alert the users in the household that another telephone is off-hook. This audible and/or visible alert at the on-hook EOH indicating telephone is over and above that audibly output by the parallel telephone which caused the receipt of the EOH signal.
