Abstract: Guard bands (20a, 20b, 20c, 20d) in a tuning fork gyroscope reduce or eliminate force and sensitivity associated with proof mass (13) motion norma l to the substrate (22) as a result of voltage transients. The guard bands reduce the undesired effects of transient voltages on electrostatic coupling of interleaved comb electrodes (12a, 18a; 14a, 18b; 14b, 18c; 12d, 18d). The guard bands are biased to reduce the coupling ratio to zero and thereby enab le starting and improved performance. Various configurations of guard bands may be employed including distinct inner (20b, 20c) and outer (20a, 20d) guard bands, distinct inner guard bands only, extended sense electrodes below inne r sensing combs with no outer guards, distinct outer guard bands with extended sense electrodes, and sense electrodes extended beneath both drive and sensi ng combs.

Granted: 2007-12-11
Abstract: Semiconductor diodes having a low forward volt-age conduction drop, a low reverse leakage current and a high voltage capability suitable for use in in-tegrated circuits as well as for discrete devices. The semiconductor diodes are fabricated as field effect de-vices having a common gate and drain connection by a process which provides very short channels, shallow drain regions and longitudinally graded junctions. Con-tinuation of the gate/drain contact layer over specially located tapered edge field oxide (34) maximizes the breakdown voltages of the devices. The preferred fab-rication technique utilizes four masking steps, all with-out any critical mask alignment requirements. Various embodiments are disclosed.

Abstract: A digital demodulator which coherently demodulates a low-IF or zero-IF complex signal using a complex-valued phase-locked loop (CPPL). The CPPL includes a numerical controlled oscillator, four multipliers and two combiners to provide independent phase/frequency and amplitude outputs. The CPLL exhibits in first order PLL dynamics without a loop filter in the feedback loop to the NCO. However a filter with one or more poles may be included in the feedback circuit to exhibit 2 nd or higher order PLL dynamics. The CPLL allows coherent demodulation of extremely low FM modulation indexes whereby the incoming frequency drift may be larger than the frequency deviation. It can also be used to coherently demodulate signals which have combined amplitude and phase characteristics.

Granted: 2003-08-05
Abstract: A currency handling system adapted to accommodate currencies of any denomination or type without having been pre-programmed with data representative of the denominations or types. The currency handling system is capable of generating such data internally, by scanning sets of master currency bills to obtain information representative of the master bills which may be used to denominate or authenticate subsequent test bills according to selected or default sensitivity levels. The master currency bills may comprise bills of different currency types, including bills from different countries. The master information may comprise numerical and/or non-numerical data. The denomination or authentication of the test bills is based on a comparison of either pre-stored or self generated master information with scanned data values associated with the test bills. Master information derived by one machine may be quickly and efficiently loaded into one or more secondary machines through a flash card loading system,

Abstract: An absolute phasing circuit having a simplified phase rotating means constituting a remapper. The phase rotation angle of a receiving phase for the signal point arrangement on the transmitting side is detected, and a phase rotation signal RT (3) based on the detected phase rotation angle is outputted from a frame synchronization circuit (2). Phases of baseband demodulated signals I and Q through a demodulator circuit (1) are rotated by 45.degree. through a ROM (3) constituting the remapper. A logic conversion circuit (4), receiving the baseband demodulated signals I and Q through the demodulator circuit (1) and phase rotated baseband demodulated signals i and q from the ROM (3), performs inversion of code and exchange of the baseband demodulated signals selectively and delivers a baseband demodulated signal matched with the signal point arrangement on the transmitting side. The circuity is simplified because the ROM (3) is simply required to rotate the phase of the baseband demodulated signals I and Q through the demodulator circuit (1) by, for example, 45.degree..

Abstract: The invention is for a system and method for performing forward error correction on an MPEG-2 transport stream that has optional error correction information embedded within the transport stream. An error correction operation is performed on a super group of packets within the transport stream. The error correction data is inserted into a created trailer group of MPEG-2 compliant transport stream packets having no payload, but only an adaptation field The trailer group packets are optional and therefore can be discarded by a standard MPEG-2 decoder, but can also be used to recover data lost in the transmission of the transport stream. The invention results in a system and method to correct an MPEG-2 transport stream that can be used in any one of the digital video broadcast (DVB) formats, without the need for error correction decoders which are specific to the DVB format.

Title: Halogenated silicone resin compositions
Inventor: LINZ RHONDA L
IPC: C08G77/442
Filed: 1998-05-21
Granted: 2009-05-19
Abstract: Halogenated resin compositions are prepared without using halogen acids by combining at least one silicone intermediate, with an optional silane, an organic halogen-containing ingredient having functional groups selected from the group consisting of hydroxy, amine, and carboxyl groups, and a resin selected from the group consisting of hydroxy- and epoxy-functional resins. One or more amine curing agent and/or catalyst selected from the group consisting of organometallic compounds, acids, bases and mixtures thereof can optionally be added to facilitate ambient temperature curing of the resulting composition.   The combined ingredients undergo hydrolysis reactions to form a halogenated organooxysilane that condenses to form a cross-linked halogenated polysiloxane composition. The resin also reacts with the condensing halogenated organooxysilane to introduce itself into the cross-linked halogenated polysiloxane and, thereby forming the halogenated polysiloxane resin composition. The composition is prepare without using an inorganic halogen acid, and is fully-cured at ambient temperature by exposure to atmospheric moisture to form a protective film, or alternatively a composite (10), having improved properties of chemical, abrasion, corrosion, weather, flame, and ultraviolet resistance.
