  • Patent number: 5151049
    Abstract: An electrical connector system is described, of the type that includes a latching arrangement for releasably holding a cover of a first connector to a second connector, which includes a pivoting latch that is resiliently biased against pivoting without the use of a spring. The cover (12, FIG. 1) has a pair of latch support brackets (80, 82) that are resiliently deflectable slightly together and apart. The latch has opposite parts each lying adjacent to one of the brackets and has a trunnion received in a hole in the bracket to pivot about a pivot axis (36) thereon. Each bracket has a slot (90, FIG. 3) extending radially with respect to the pivot axis (36), and each latch part has a rib (108) partially received in a slot, with each side (110, 112) of the rib being angled from parallelism with the pivot axis. As the latch pivots, the ribs deflect the brackets apart, to provide a spring force urging the latch to pivot back.

  • Patent number: 5150410
    Abstract: A secure narrowband digital conferencing system is capable of handing multiple speakers simultaneously and in a full duplex mode. The system uses a multipulse or a code-excited linear predictive (CELP) speech processing algorithm for colding the speech signals of the respective participants. A conference director receives the multipluse or CELP encrypted voice signal streams over normal telephone links, decrypts them, then synthesizes a composite speech signal and uses an analysis-by-synthesis algorithm to compress them, and then encrypts the composite signal and transmits it back to all the participants.

  • Patent number: 5150201
    Abstract: A digital television-signal-processing circuit for a composite color signal is sampled with a first clock signal. The digitized composite color signal is reconverted with a line-locked second clock signal. The two clock signals have the same frequency. A second phase-locked loop for controlling the phase of the horizontal pulse includes a locked oscillator and is loosely coupled to a first phase-locked loop which generates a horizontal reference clock. The decoupling of the data, which is referred to the two clock signals, takes place in a dual-port read/write memory which is written into synchronously with the first clock signal and read from synchronously with the second clock signal.

  • Patent number: 5146225
    Abstract: A CMOS circuit for averaging digital-to-analog converters includes a shift register of series-connected master and slave cells controlled by a shift clock. The input of the shift register is supplied with a pulse-density-modulated data signal, and the outputs of each of the master and slave cells are connected to a data-dependent control input of a multistage gate circuit. The gate circuits are controlled by a gate clock and cause constant currents to be switched via two buses to the input and output of a p-channel current mirror in accordance with the state of the master or slave cell. The input of a current mirror is constantly supplied with one-half the sum current of the constant-current sources, and the current mirror provides current scaling, preferably by a factor of 0.5.

  • Patent number: 5138567
    Abstract: In a median filter, signals received at the input are fed to a cascade of delay elements whose number is equal to the degree N of the median filter. The signals at the outputs of the delay elements which preceded the signal received at the input are fed to N subtracters which form the differences between the signal at the input and the N preceding signals. The signs of the differences are stored in shift registers, and upon receipt of a new signal at the input, they are shifted by one place. From the signs of the differences, the selection unit determines the median as the signal for which N/2 differences have negative signs and N/2 differences have positive signs.
