Title: Providing speakerphone operation in a portable communication device
Inventor: NICHOLLS RICHARD BRENT
IPC: H04B3/20
Filed: 1999-07-21
Abstract: A portable communication device 104, such as a cellular telephone, is operable in a speakerphone mode. The communication device uses a digital communication scheme, and both receives and generates vocoded signals. The speakerphone provides half duplex operation to eliminate echo. When voice activity is detected, the device activates a speaker and mutes a microphone to avoid echo. When no voice activity is detected in the received signal, the speaker is muted and the microphone activated. To determine when speech activity is present in the received signal, a novel voice activity detection (VAD) algorithm is used which takes advantage of parameters provided as part of the received vocoded signal. The VAD algorithm calculates a staggered average value (SAV), which is proportional to the frame energy value of the vocoded signal, and compares this value with a threshold voice indicator value to determine the presence of voice activity. Muting of the microphone may be achieved by adjusting the echo threshold of the telephone's digital signal processor (210, fig.2).

Title: Reduced impact solenoid operated valve
Inventor: BENSON DONALD J
IPC: F16K31/06
Filed: 1999-11-12
Abstract: A solenoid actuated flow control valve assembly (10) includes a valve plunger (14), a solenoid actuator (16) including a coil (32) and an armature (54). An armature overtravel feature (18) permits continued movement of armature (54) relative to plunger (14) from an engaged position into a disengaged position when the valve plunger (14) reaches a closed position. The armature overtravel feature (18) includes an overtravel biasing spring (60) for returning the armature (54) from the disengaged position to the engaged position prior to subsequent energization of the actuator coil (32). The overtravel feature (18) minimizes the mass impacting the valve seat (48) thereby extending seat life while avoiding lost motion in the armature (54) during the next actuation cycle. The flow control valve also includes an armature protecting feature (68) in the form of a shim (70) and sleeve (56) for minimizing armature wear by preventing the armature (54) from contacting the valve plunger (14) and an armature stop (66). The valve is used in fuel injection systems of IC engines.

Title: Multiplexed digital packet telephone system
IPC: H04B1/66
Filed: 1986-08-19
Abstract: An efficient system for simultaneously conveying a large number of telephone conversations over a much smaller number of relatively low-bandwidth digital communication channels is disclosed. Each incoming telephone speech signal is filtered, periodically sampled, and digitized. An efficient computational speech compression algorithm is applied to transform a sequence of digitized speech samples into a much shorter sequence of compression variables. The compression variable sequence is further processed to construct a minimum-length bit string, and an identifying header is appended to form a packet. Only a few packets containing information on representative background noise are generated during pauses in speech, thereby conserving digital bandwidth. The packets are queued and transmitted asynchronously over the first available serial digital communication channel. Numerical feedback to the compression algorithm is employed which results in the packet size being reduced during periods of high digital channel usage. Packet header information is utilized to establish a "virtual circuit" between sender and receiver.

IPC: G03G15/11
Filed: 1979-01-31
Abstract: PURPOSE:To obtain the elastic roller of the characteristics uniform over the entire peripheral surface by contracting the outside diameter of an elastic foam roller in a low pressure atmosphere and inserting the same in net-form body then releasing the low pressure atmosphere and pressure-contacting the outside peripheral surface of the roller to the inside peripheral surface of the net-form body. CONSTITUTION:An elastic foam roller 6 is inserted into a bag 10 composed of a water soluble macromolecular film and the opening end of the bag 10 is sealed, after which the inside of the bag 10 is reduced pressure by a suction device 12 through a conduit 11 to allow the outside diameter of the roller 6 to contract and become smaller than the inside diameter of the net-form body 9. Next, the roller 6 covered and contracted by the bag 10 is inserted into the spacing in the net-form body 9 and when the inside of the bag 10 is returned to the atmospheric pressure after this, the roller 6 tries to restore and its outside peripheral surface makes close contact with the inside peripheral surface of the net-form body 9 owing to its elastic repulsion  force. Thence, this assembly is dipped in a hot water bath to elute away only the  bag 10 from the assembly. In this way, the elastic form roller which is free from  breakage and twist in the foam and has even elastic pressure on its outside peripheral surface is obtained.
