摘要:
A system and method for wirelessly exchanging an encryption key between a first device and a second device. The system generally includes: a transmitter, provided to the first device, for transmitting a signal that is strong enough to transmit over a predetermined distance while having a strength that decreases exponentially with distance, for example a magnetic field signal; a receiver, for example a Hall effect switch, provided to the second device, for receiving the signal; and a controller for determining when the first device and the second device are within the predetermined distance and controlling the transmitter to transmit the encryption key based on the determination.
摘要:
A method and apparatus for transferring data from a first electronic device to a second electronic device, both first and second electronic devices having Universal Serial Bus (USB) client interfaces, the method comprising the steps: connecting the two electronic devices with a USB cable; toggling the voltage on a VBUS line of the USB cable between logic high voltage and no voltage at the first electronic device; detecting toggles of the VBUS line at the second electronic device; and interpreting the toggles detected in the detecting step as data.

A system for adjusting a deflector in a seismic survey comprises a generally upright deflector body and at least one bridle connected to a seismic cable. The bridle includes an upper segment secured to an upper connection point on the deflector body, and a lower segment coupled to a lower connection point on the deflector body. The upper bridle segment, lower bridle segment and deflector body define a geometry between themselves. This geometry is adjustable by at least one actuator so as to control the tilt angle of the deflector body.

A handheld electronic device having a microprocessor housed within a body including a display area and a contact-sensitive area is disclosed. The contact-sensitive area detects contact engagement therewith and produces instruction data based thereupon. A microprocessor-run software program receives instruction data from the contact-sensitive area. The contact-sensitive area has a home zone area and a plurality of activity launch zone areas. The software program is programmed to process the instruction data and determine sweeping contact motion detected on the contact-sensitive area originating at the home zone area and terminating at one of the plurality of activity launch zone areas. The program responsively launches an operator-instructed activity corresponding to the activity launch zone area at which the sweeping contact motion terminated.

A mobile device, through the use of an NFC subsystem, may determine holster-proximity information, i.e., whether the mobile device is near to (including in) a holster or out of, and away from, the holster. The holster-proximity information may be used by the mobile device to enter into a user-inactive mode. Such entry into a user-inactive mode may involve disabling user interface components, such as input devices and output devices. In particular, the holster-proximity information may be used by the mobile device to disable the keyboard, that is, prevent presses on keys in the keyboard from being recorded. Such disabling may be considered of particular importance when the mobile device is going into and coming out of the holster.

A portable electronic device includes a portable housing, and a battery and pointing device carried by the portable housing. The portable electronic device further includes electronic circuitry carried by the portable housing and connected to the battery and the pointing device. The electronic circuitry may switch from a sleep mode to an active mode based upon operation of the pointing device in a non-random pattern, and not switch from the sleep mode to the active mode based upon operation of the pointing device in a random pattern.

A communication system may include a transaction terminal configured to perform a transaction based upon receiving account information, a first NFC device(s), and a mobile wireless communication device. The mobile device may include a second NFC device configured to communicate with the first NFC device(s) upon being swiped therewith, a memory configured to store account information associated with different accounts and store respective account swipe patterns for the different accounts, where each account swipe pattern comprising at least one of a set time or a set number of swipes, and a controller. The controller may be configured to detect a swipe pattern, determine whether the detected swipe pattern corresponds to one of the plurality of stored account swipe patterns, determine a respective account based upon the determined corresponding stored account swipe pattern, and communicate the associated account information for the determined respective account to the transaction terminal.
摘要:
A communications system may include a plurality of electronic devices each configured to wirelessly communicate via an NFC format and another wireless communications format(s). A first electronic device may have an NFC transfer parameter associated therewith, and may be configured to establish an NFC link with a second electronic device of the plurality of electronic devices when in proximity therewith, designate data to be transferred to the second electronic device, and determine whether the designated data complies with the NFC transfer parameter. Based on a determination that the designated data complies with the NFC transfer parameter, the first electronic device may be configured to transfer at least some of the designated data via the NFC link, and otherwise transfer at least some of the designated data to the second electronic device over a separate wireless communications link using the at least one other wireless communications format.

A wireless communications system may include a first electronic device comprising a first media content playback device, a first wireless transceiver, and a first controller coupled with the first media content playback device and the first wireless transceiver. The system may further include a second electronic device comprising a second media content playback device, a second wireless transceiver configured to wirelessly communicate with the first wireless transceiver, and a second controller coupled with the second media content playback device and the second wireless transceiver. The first controller may be configured to generate a playback pointer associated with playback of given media content, and wirelessly communicate the playback pointer to the second controller. The second controller may be configured to play back the given media content based upon the playback pointer, and without receiving the given media content from the first electronic device.
