  • Patent number: 8035466
    Abstract: A coaxial to transmission line connector has a connector and an attachment area with a windowed electrical attachment point that when soldered in place on a ground reference of an electrical device, creates an electrical and mechanical connection between an outer conductor of the coaxial to transmission line connector. The attachment area has at least one mechanical alignment point and a corresponding reference pivot point located substantially co-planar at the termination of the coaxial dielectric region at an edge of a PCB and a port of the coaxial to transmission line connector. The at least one mechanical alignment point and the corresponding reference pivot plane serve to automatically align the coaxial to transmission line connector to the electrical device. Opposite the attachment area is a dielectric area following termination of the outer conductor in the transition area of the microstrip transmission line.

  • Patent number: 5848355
    Abstract: An automatic frequency control is implemented in a selective call receiver (100) having a controllable frequency synthesizer (203). The output frequency of the synthesizer an is derived from a frequency reference element (205).

  • Patent number: 5761615
    Abstract: A low power zero-IF selective call receiver has a local oscillator (106) that generates an injection signal for a first mixer (104) and a pair of quadrature phase related injection signals (122, 124) for a pair of second mixers (112, 114).

A digital phase shifter/divider (116) coupled to the local oscillator (106) generates the pair of quadrature phase related injection signals (122, 124) at the frequency of the intermediate signal (108) which also equals the frequency of the local oscillator (106) divided by an integer greater then 1. The pair of second mixers (112, 114) coupled to the digital phase shifter/divider (116) converts the in and quadrature phase components (122, 124) of the intermediate signal (108) to respective in and quadrature phase baseband signals (126, 128).

  • Patent number: 5748082
    Abstract: A light sensitive switch for the activation of an alerting circuit (70) to be used as an electronic alerting device (50). Alerting device (50) may be used in publications such as a magazine (78) or book (94) to enhance the printed material by audio visual and/or mechanical vibration means. A photosensor (52) is used to detect ambient light when the publication is opened to an activation page (86) where the enhancement is located. Photosensor (52) switches on a transistor (66) when exposed to light, which in turn switches on alerting circuit (70). Alerting circuit (70) may consist of an audio transducer (74), a lamp (76), a motor (128), a solenoid (136), a mechanical vibrator or any combination of these. Pages are used to block ambient light from photosensor (52) when the publication is closed, thus turning off alerting device (50).

  • Patent number: 5666350
    Abstract: An apparatus codes excitation parameters for very low bit rate voice messaging using a method that processes a voice message to generating speech parameters. The speech parameters are separated (316) to produce a first group of energy parameters and a second group of pitch and voicing parameters. Subsequently, the first group of energy parameters are encoded and compressed using a non-uniform root-mean-square scalar process (318) to create a first plurality of encoded data. Additionally, the second group of pitch and voicing parameters are compressed, encoded, and combined into a single parameter using a three slope vector encoding process (320) that creates a second plurality of encoded data. Finally, the first and second plurality of encoded data are multiplexed (322) to create a multiplexed signal for transmission, the multiplexed signal representing the voice message.
