Title: Decision directed phase detector
Inventor: PERLOW RANDALL BRET
IPC: H04N5/44
Filed: 1999-05-18
Granted: 2001-08-21
Abstract: A decision directed phase detector that uses the quantized data output from a slicer to aid the phase error detection process to determine a phase error of a complex signal such as a vestigial sideband (VSB) signal containing in phase (I) and quadrature phase (Q) components (I and Q signals). The phase detector comprises subtractor having one input coupled to the I signal and a second input coupled to the data output of the slicer representing the magnitude of a sample point within a symbol. The quantized signal is subtracted from the I signal to produce ΔI signal. The Q signal is processed to determine its sign and magnitude. The sign and magnitude values are multiplied together and the result is multiplied with the ΔI signal to produce the phase error between the I and Q signals. This phase error signal is used in a digital television receiver to extract a data signal from a VSB signal for demodulation.

Abstract: There is provided a precise and automatic method for putting a ring on a drilling head dedicated to drill a PC board and its device. There are arranged a material-supply region and a material-output region on the two sides of a processing rotatable platen. On the periphery of the rotatable platen, there are arranged a drill-insertion region, a ring-release region, a ring-catch region a diameter-measure region, a drill-taking region and a drill-removing region. A drill box loaded with a plurality of drilling heads is placed in the material supply region, and moved to the drill-insertion region by stepping. The plurality of drilling heads in the drill box are sequentially inserted into equally spaced norm seats arranged on the rotatable platen. By the stepping rotation of the rotatable platen, each drilling head is able to enter the ring-release region to remove the nominal ring that has lost its precision, and then enter the ring-catch region for measuring by CCD. The auxiliary ring-looping mechanism fetches the actual precision of the drill sleeved with the nominal ring. Then, the drilling head with a ring is moved to the diameter-measure region for measuring by CCD and recognizing the good units and defective units for the drill diameter and the knife-edge angle, so that the good unit of the drill with a ring can be moved to drill-taking region for outputting material to be placed in the drill box on the material output region, or the defective unit of the drill with a ring can be moved to drill-removing region for exhausting material. Therefore, a precision operation for putting rings can be completed automatically to make the drilling apparatus easy in controlling the drilling precision in the drilling process of the PC board.

Title: Control channel for time division multiple access systems
Inventor: KRISHNAMOORTHY RAJEEV
IPC: H04B1/7075
Filed: 2000-05-15
Granted: 2002-11-11
Abstract: In a TDMA system a multifunction control channel is employed that carries data used for implementing channel access functionality for users and is also employed at the remote terminals in the performance of modem functionality. In other words, information necessary to accurately receive data on the user traffic channels is obtainable by processing the multifunction control channel. This is achieved by arranging the broadband channel of the TDMA system as a repeating frame having time slots in which at least one time slot is reserved for use as the multifunction control channel, and the data that is transmitted on the multifunction control channel is encoded using a spread spectrum format. To this end the data carried on the multifunction control channel is encoded in a way that uses each symbol of the multifunction control channel as if it were a so-called spread spectrum ""chip"". At least one of the remaining time slots of the frame, and preferably all of the remaining time slots, which are typically used to carry user traffic arranged as logical channels, are not spread spectrum encoded. With regard to modem functionality, the remote terminals use the received multifunction control channel to (a) perform frame synchronization, i.e., frame timing, (b) perform frequency offset estimation, (c) obtain an estimate of the channel impulse response, and (d) estimate the received signal strength for use in gain control.
