Abstract: A method and system for managing automated devices within a multi-dwelling unit. In particular, the present invention relates to a system and method enabling individual tenants to control the automated devices within their respective units and for a building manager or administrator to access and control automated devices for all units within the multi-dwelling units.

Abstract: A delay line clock multiplier is disclosed for use in a communication system, in which a delay line is used as a clock multiplier for generating a higher speed clock that may be used, for example, for data sampling. The speed and timing characteristics of the clock delay line are adjusted by controlling the supply voltage to the delay line. because proper synchronization may be achieved at the higher frequencies using an oversampling synchronization approach which in turn is made possible by the delay line clock multiplier which allows for the oversampling of a signal at sub-interval increments.

Abstract: Performing soft error correction includes receiving a word at a soft correction engine (310a, 310b) capable of operating in more than one correction mode, identifying soft bit positions within the word, and automatically generating a number of possible results (370) for the received word using combinations of the soft bit positions and more than one correction mode. The soft correction engine (310a, 310b) may include a Golay engine.

Abstract: A filter is created by sampling noise during an inter-frame gap (110) of a received signal, sampling a data frame preamble (115) from within a data frame (105) of the received signal, and computing filter coefficients based on the noise sampled during the inter-frame gap (110) and the data frame preamble (115) sampled from within the data frame (105).

Abstract: This disclosure relates to varying load and modulation applied to each of multiple frequency subchannels based on anticipated attenuation experienced by those subchannels. Communicating data includes identifying a static component of a transmission medium for wideband communications having at least two subchannels (110), determining a function of noise or attenuation versus frequency for the static component (120), selecting wideband modulation schemes for the subchannels based on the function determined (130), and communicating a data signal over the subchannels (145). The transmission medium includes a medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multitenant units and multi-dwelling buildings. Independent demodulation functions may be applied to at least two of the subchannels.

Abstract: An order filling system used in an inventory storage area having a controlling computer and a network of user interface devices which each have a microprocessor, memory and the ability to independently process information. The controlling computer coordinates communications with the user interface devices through poll broadcasts. The controlling computer transmits order information to the user interface devices which display the order information to assist workers in picking inventory order items. When the workers pick the specified quantity of an order items they press confirmation buttons on the user interface devices which transmit confirmation signals to the controlling computer. If special processing is required, the user interface device is capable of performing various tasks which reduces the processing requirements of the controlling computer.
