Title: Frequency and time slot synchronization using adaptive filtering
Inventor: ARORA ARVIND S
IPC: H04B7/26
Filed: 1991-12-11
Granted: 1997-02-25
Abstract: The synchronization process of the present invention fil-ters the received signal with an adaptive band-pass filter (101) while buffering the received signal in memory (108). The en-ergies of the input signal and the filtered signal are estimated (103 and 104) and the gain of the filter is adapted (105) based on the difference between the energies. The pole of the filter is adapted (102) to center the frequency of the input signal in the filter's pass-band. If a tone is detected (106), the length of the tone is determined (107) to ascertain if it is a frequency correc-tion burst (FCB). If the tone detected is an FCB, the signal in the memory is also the FCB that is then filtered in the band-pass filter (101) and the difference between the frequency of this signal ant 67.5 kHz is determined (109). This difference represents the frequency offset between the base station car-rier frequency and that of the mobile radiotelephone, and can be fed into the local oscillating means to compensate for the frequency offset. The boundaries of the FCB establish the time slot alignment of the TDMA structure being received from the base station.

Title: Step-dimming magnetic regulator for discharge lamps
Inventor: NUCKOLLS JOE A
IPC: H05B41/42
Filed: 1992-08-27
Granted: 2002-06-04
Abstract: A dimming system for a discharge lamp has a magnetic regulator with first, second and third windings linked by a magnetic core, the first winding being connectable to a source of alternating current. The second winding and a starting circuit are connected to the lamp for lighting the lamp. The third winding is tapped and has a ballast capacitor connected across the winding. An inductive reactor and relay contact set are connected in series between one end of the third winding and the tap so that when the contact set closes, the reactor stores energy from the source and reduces the power to the lamp, abruptly reducing its light output. A motion-responsive detector is used to energize the relay. With a normally closed contact set, the lamp is dimmed until a moving person is detected, opening the contact set and increasing the lamp light output. Multiple lamps can be controlled simultaneously.

Title: Transient suppression circuit for a time domain duplex transceiver
Inventor: HECK JOSEPH P
IPC: H04B1/48
Filed: 1991-08-13
Granted: 1997-09-16
Abstract: A radio transceiver (100) is coupled to a source of a reference waveform (13), and includes transmit mode receive modes. The transceiver (100) comprises a first down mixer (16), a first low pass filter (20) coupled to the first down mixer, and a first selective coupling switch (S1). The first down mixer (16) is coupled to receive an input signal having an input frequency, for mixing the input signal with the reference waveform to produce a first signal. The first signal has a frequency substantially lower than the input frequency. The first low pass filter (20) is coupled to the first down mixer (16) for producing a filtered first signal. The first selective coupling switch (S1) couples the first down mixer (16) and the low pass filter (20) when the radio transceiver (100) is in the receive mode, and decouples the first down mixer (16) and the low pass filter (20) when the radio transceiver (100) is in the transmit mode, thus substantially eliminating transient disturbances.

The retainer is rotatable between first and second positions, wherein in the first position the attachment means is  exposed  for user  access  thereto,  and  in  the  second position, the cap cooperates with the spool to retain the cord on the cord receiving surface.  The retainer may be provided with force transfer means to allow the user to wind up the cord about the spool during initial installation of the device.    Means may also be provided to fixedly engage the ends of a pair of free-ended cords, as are typically found in venetian blinds.  A bushing provides non-binding rotation of the spool about its spindle.
