摘要:
An inverted telescoping mast configured to be mounted to a ceiling or other structure within a building for supporting a payload at a range of heights within the building. The mast can include cable management for routing of cables external the mast for supplying/exchanging power, control signals, data etc. to the payload. An internal spring retains the mast in the retracted position. A tension control system restricts extension and/or retraction of the mast when actuating cable tension is above or below respective tension thresholds.

A method for enabling a person who cannot talk but who is familiar with use of anonym moveable picture communication to autonomously communicate speech sound automatically in a sequence, and may include: choosing a plurality of selected encoded tags that are transitionable between a ready mode in which the tag is proximate to an associated tag reader and a go mode in which the tag is in operative association with the associated tag reader. In the go mode, the selected plurality of the encoded tags are read in a sequence to provide a series of coded signals, a sound file corresponding to the series of coded signals is transmitted to an audio output device to convert the sound file automatically into the speech sound.

One embodiment of the present disclosure provides a system and associated processes for monitoring a customer's product purchases and product consumption. Further, the system enables the customer to maintain customer-selected preferences by presenting to the customer product information associated with the customer preferences and a product. In one embodiment, the system can monitor the consumption of products over a predefined period of time to facilitate the customer maintaining the customer preferences over the predefined period of time. In one embodiment, the system can present alternative product purchases based on a selected product and the customer preferences. In one embodiment, the system can facilitate monitoring nutrition consumption. In one embodiment, the system can facilitate monitoring pharmaceutical use. In one embodiment, the system can facilitate the customer making environmentally conscious purchases. In one embodiment, the system can present the customer with environmental offset options to help maintain customer environmental preferences.

A circuit breaker and method includes a mechanical pole moveable between a latched position and an unlatched position to open an electrical connection between a pair of electrical contacts. An electronic tripping device is configured to respond to a sensor signal. The sensor signal is output from a condition sensor wherein upon receiving the sensor signal the electronic tripping device trips the mechanical pole into the unlatched position.

A method for automatic auction extension and user controlled standardized bid increment/decrement. The method is implemented in an electronic commerce exchange. The auction method implements automatic extension of an auction in response to bidding activity from auction participants. The method includes the step of setting an end time for concluding the auction. Bids are received from remote bidders via a distributed computer network. The received bids are analyzed to determine whether a predetermined number of bids are received within a predetermined time of the auction end time. If a greater number of bids are received within the predetermined time, the duration of the auction is automatically extended and a new auction end time is set. The auction participants are notified of the new auction end time. Standardized bid increments can be set defining a minimum amount at which a subsequent bid differs from a previous bid. Similarly, standardized bid decrements can be set defining a minimum amount at which a subsequent bid subsequent bid differs from a previous bid. A total number of possible extensions can be set defining a number of times the auction can be extended due to bidding activity. The settings can be changed dynamically during the auction by the auction operator/user.
摘要:
A timing recovery system and method for accelerated clock synchronization of remotely distributed electronic devices is provided. The system includes a phase locked loop, a linear estimator and control logic. The method includes sampling a clock signal received from an electronic device, applying a linear estimation technique to estimate the frequency and phase of the received signal and providing those estimates to a phase locked loop to accelerate the phase locked loop acquisition rate and secure signal lock quickly.
摘要:
A communications management system introduces a low bandwidth phase locked loop (LoBW-PLL) working in tandem with a high bandwidth phase locked loop (HiBW-PLL). The LoBW-PLL only needs to follow the average frequency of the transported clock and not all of the excursions made by the master clock. During periods of downstream outage, the LoBW-PLL opens its loop and free wheels such that disturbances caused by a reacquisition do not impact the concept of time for the LoBW-PLL. After reacquisition, the LoBW-PLL and HiBW-PLL are compared to determine if a timing error has occurred. If a timing error is detected, the magnitude of the timing error is measured upon completion of the reacquisition cycle, and this measurement is used to correct the timing error.
