Abstract: A dual-range crystal oscillator module comprises lower and upper wiring board panels each having a component side, a surface mount side, a central portion and an outer edge portion including a plurality of input-output contacts. A lower set of crystal oscillator components is mounted to the lower wiring board panel such that the lower set and the lower wiring board panel define a first crystal oscillator circuit. An upper set of crystal oscillator components is mounted to upper wiring board panel such that the upper set of crystal oscillator components and the upper wiring board panel together define a second crystal oscillator circuit. A side-wall frame is attached between the upper and the lower wiring boards providing connections between the input-output contacts of the upper wiring board panel and the input-output contacts of the lower wiring panel.
Abstract: A joystick has a base and a cover mounted over the base. A stick has a first end extending from the cover and a second end. A gimbal has a first and second yoke that are coupled to the stick to allow the stick to move. The yokes each have a first and second end. A pair of wipers is mounted to the first ends of the yokes. A pair of resistors is positioned between the wipers and the base. The resistors are adapted to generate an electrical output signal indicative of a position of the stick when a voltage is applied to the resistors. Several terminals are mounted to the base. A first portion of the terminals are electrically connected to the resistors. A switch is positioned in the base below the second end of the first yoke. The switch is activated when the first yoke is sufficiently rotated so as to cause the second end of the first yoke to contact the switch and to close the switch.
Abstract: A seat belt tension sensor is attached to a seat belt in a vehicle. The seat belt tension sensor includes a housing attached between the vehicle and the seat belt. A limit structure is located in the housing. A sensor is attached to the limit structure for generating an electrical signal in response to the sensor being placed in tension. The electrical signal changes as a function of tension on the seat belt. The limit structure moves between a first position in which the limit structure transfers the seat belt tension to the sensor and a second position in which the limit structure transfers the seat belt tension to the housing.

Abstract: A duplexing filter 10 suitable for use in a mobile communication system. The filter 10 has a core of dielectric material 12 with several through holes 30 that define resonators 25. The core 12 has metallized surfaces 16, 18, 20, 22 and 24 except for the top surface 14. Several metallized resonator pads 60 surround each of the through holes 30 on the top surface 14. A metallized serpentine region 61, 62 extends from one or more of the resonator pads 60 toward a side surface 18 of the core 12. The metallized serpentine region 61, 62 causes attenuation of a third harmonic frequency.

Abstract: An ovenized oscillator has two ovens. One of the ovens is heated by a heater and the other is cooled by a thermoelectric module. The ovenized oscillator has an inner oven with an oscillator located inside. A thermoelectric heat pump cools the inner oven. An outer oven contains the inner oven and the thermoelectric heat pump. A heater heats the outer oven. The ovenized oscillator is operated with the inner oven temperature being lower than the outer oven temperature to improve component life and reduce crystal aging.

Abstract: An array resistor network that has a high density of resistors per unit area. The array resistor network includes a ceramic substrate having a top and bottom surface. Apertures extend through the substrate between the top and bottom surfaces. Recesses are located on opposite edges of the substrate. Resistors are located on the top surface. Each resistor is located between a recess and an apertures. Inner conductors are connected to one end of the resistors. The Inner conductors are located on the top surface and extend through the aperture onto the bottom surface. Outer conductors are connected to another end of the resistors. The outer conductors are located on the top surface and extend along the recess onto the second surface.
Abstract: An oscillator assembly has a voltage controlled crystal oscillator that produces a stable reference frequency. The voltage controlled crystal oscillator is connected to an electronic frequency adjust voltage. A temperature compensation circuit is connected to the voltage controlled crystal oscillator. The temperature compensation circuit provides a temperature compensation voltage to the voltage controlled crystal oscillator. A trim effect compensation circuit is connected between the temperature compensation circuit and the electronic frequency adjust voltage. The trim effect compensation circuit adjusts the temperature compensation voltage in response to a change in the electronic frequency adjust voltage.
Abstract: A low temperature co-fired ceramic assembly (LTCC) with a constraining core to minimize shrinkage of outer ceramic layers during firing. The outer ceramic layers have high density circuit features. A ceramic core includes several ceramic layers. Several via holes are located in the first and second ceramic layers. Several low density circuit features are located on the ceramic layers that make up the core. Outer ceramic layers are placed top and bottom of the ceramic core. The outer ceramic layers have via holes and high density circuit features. The circuit features patterned on the ceramic layers include resistors, capacitors, circuit lines, vias, inductors, or bond pads. The ceramic core is fired first in a furnace. The outer layers are then laminated to the ceramic core and fired. The ceramic core controls the shrinkage rate of the outer ceramic layers during firing allowing higher density circuit features on the outer layers.
Abstract: A miniature ovenized crystal oscillator has a ceramic case that has a cavity, a bottom and a ledge that extends into the cavity. The case has several circuit lines. A substrate is located in the cavity and is supported by the ledge. The substrate has a top and bottom surface and several circuit lines. A crystal is mounted to the bottom surface of the substrate and is connected to the substrate circuit lines. A signal conditioning circuit is mounted to the top surface of the substrate and is connected to the substrate circuit lines. The case circuit lines are connected to the substrate circuit lines by a conductive epoxy. A heater is mounted to the bottom of the ceramic case. A thermal adhesive is located between the heater and the crystal. The thermal adhesive thermally links the crystal and the heater.
Abstract: An eccentricity compensator for preventing wear induced rotational displacement. The eccentricity compensator is mounted between two rotating shafts joined by a torsion bar that have non-coaxial axes of rotation. The compensator includes a first ring attached to a first shaft and a second ring located adjacent the first ring. A third ring is attached to a second shaft and the third ring is located adjacent the second ring. One or more pin-slot pairs are located between any two of the first, second or third rings. A spring is mounted adjacent each pin-slot pair. The spring biases the pin-slot pair such that hysteresis is prevented.
