  • Patent number: 8781142
    Abstract: Systems and methods enhancing auditory experience for a user are provided. The method comprises receiving ambient sound by way of one or more microphones positioned about a user; monitoring the user's movements to determine sound signals interesting to the user; processing the received ambient sound based on the user's movements to at least: increase inclusion of the interesting sound signals in a generated audio output; or reduce inclusion of uninteresting sound signals in the generated audio output.

  • Patent number: 7173944
    Abstract: A digital subscriber line (DSL) communication system that utilizes the high frequency band of a standard telephone line does not require the use of a plain old telephone service (POTS) splitter in the resident's home, which provided isolation between the POTS frequency band (0 to 4 kHz) and the DSL frequency band. A digital subscriber line modem utilizes either constant envelope modulation or quadrature amplitude modulation for outputting DSL signals upstream to a central office. When a telephone in the resident's home is detected as being off-hook, then the constant envelope modulation is used by the DSL modem in order to lessen the intermodulation product distortion that results in audible noise heard by a user of the telephone. When the telephone is on-hook, then another type of modulation, such as QAM, is used to maximize the upstream data rate capability in the DSL frequency band, since any noise generated by the QAM is not a problem due to the non-use of the POTS frequency band.

  • Patent number: 6212227
    Abstract: A digital subscriber line (DSL) communication system that utilizes the high frequency band of a standard telephone line does not require the use of a plain old telephone service (POTS) splitter in the resident's home, which provided isolation between the POTS frequency band (0 to 4 kHz) and the DSL frequency band. Digital signal processing techniques are utilized to adapt to varying subscriber line conditions due to POTS telephone equipment. The digital signal processing techniques eliminate the need for a splitter by reducing susceptibility to distortion due to varying subscriber line characteristics. The digital subscriber line modem utilizes constant envelope modulated signals and frequency division multiplexing, where the constant envelope modulations lessens the intermodulation distortion products due to DSL signals that are transmitted by the modem and which may result in audible noise at the POTS telephone equipment due to non-linearities of the POTS telephone equipment.

  • Patent number: 4761732
    Abstract: An interrupt controller circuit arrangement is used for encoding and storing "interrupt" signals indicating random (asynchronous) occurrence of corresponding events and for delivering corresponding "interrupt" (alarm command) signals to a (synchronous) microprocessor corresponding to the events as they occur. The events are divided into two (or more) sets in order to reduce the required number of latches and to increase the speed of operation. One (or more) of these sets consists of events which never can occur "simultaneously" (i.e., which are mutually exclusive in the sense that (within each of such sets) not more than a single one of the events can occur--and can occur only once--within a prescribed amount of time); the remaining set consists of the remaining events--i.e., those which can occur "simultaneously" or can occur simultaneously with one or more of those in the other set(s).

  • Patent number: 4525776
    Abstract: A digital computer is arranged to process data through an arithmetic logic unit in response to instructions residing sequentially in an instruction register, each instruction requiring a single instruction interval for fetching data from a selected source in a store, processing the data in the arithmetic logic unit, and storing the result of processing the data into a selected destination in the store. Means are provided for moving a single bit from any selected one of a plurality of bit positions in the selected source to any selected bit position of a plurality of bit positions in the selected destination during a single instruction interval without affecting the state of any other bit of the selected destination.

  • Patent number: 4310881
    Abstract: In a conditional transfer control circuit (10) for a controller (11) arranged for fetching instructions from a sequence of addresses wherein a list of instructions is stored, there is a circuit (25) for producing a first signal (C) representing a true or false condition resulting from executing an instruction in the list of instructions and a circuit (IRO) for producing applying a second signal (on lead 32 or 72) indicating whether control is determined by the first signal being true or by the first signal being false. An EXCLUSIVE NOR (or EXCLUSIVE OR) gate (30 or 70), responsive to the first and second signals, produces a condition transfer signal (on lead 18) that causes the controller to fetch a next subsequent instruction from an address other than the next subsequent address in the sequence of addresses wherein the list of instructions is stored.
