Abstract: A D.C. modulated phase locked oscillator (60, 80, 100, 140, 160, 190, 220, 264, or 290) includes a phase locking oscil-lator (70, 90, 128, 180, 192, 222, 266, or 292) and a D.C. modu-lator (72, 92, 130, 156, 182, 194, 224, 268, or 294). Both a for-ward path (14) and a feedback path (16) are D.C. modulated. D.C. modulation of the feed-back path (16) optionally in-cludes changing the frequency in the feedback path (16) as a function of the frequency of a modulation oscillator (64), changing the frequency in the feedback path (16) by a plurali-ty of pulses for each cycle of the modulation oscillator (64), removing pulses from the feed-back path (16), adding pulses to the feedback path (16), dividing the frequency in the feedback path (16) by higher and lower dividing ratios, preventing one cycle in the feedback path (16) from developing a "high" in the feedback path (16), holding a "high" in the feedback path (16) between two adjacent pulses, mixing quadrature frequencies with the feedback frequency in the feedback path (16), changing one input to a variable modulus divider (48) by means of a parallel adder (272), and using logic elements (148) to remove pulses from the feed-back path (16).

Title: Multiple serial access memory for use in feedback systems such as motion compensated television
Inventor: SHEN PAUL
IPC: H04N7/32
Filed: 1992-11-04
Granted: 2000-05-02
Abstract: A multiple serial access memory is provided. A dynamic random access memory (30) is addressed to input data thereto and output data therefrom. Rows of data are output from the array (50) in response to address signals (34, 36, 38) provided thereto. A plurality of serial output ports (44, 46, 48) is coupled to the output of the array for selectively latching different rows of data output from the array. The serial output ports (44, 46, 48) are clocked to output the latched data therefrom. In an illustrated embodiment, each of the serial output ports contains a shift register (62, 64, 66, ... 68) having a length equal to the width of the memory array (30). The shift register is responsive to a first timing signal (42, 52) for latching a row of data from the array (30). A second timing signal actuates the shift register to shift a row of latched data. A serial access selector (70) coupled to the shift register outputs a selected portion of the shifted data from the serial output pork. The memory has particular application as the frame store for a motion compensated interframe image coding/decoding system.

Inventor: JONES RONALD M
IPC: G01N33/92
Filed: 1991-07-15
Granted: 1999-08-31
Abstract: An assay device (14) for measuring the concentration of a soluble analyte, such as HDL-associated cholesterol, in a fluid sample, containing interfering compounds; such as LDL-; or YLDL-associated cholesterol, which can be selectively precipitated. The device includes a sieving matrix (26) capable of separating soluble and precipitated material migrating through the matrix, and a reservoir (34) which holds a precipitating agent which is effective, within a given concentration range, to selectively precipitate the interfering compounds. The reservoir is designed to delay the release of agent, on contact with the fluid sample, to maintain the concentration of precipitating agent in contact with the fluid sample within the given concentration range. The device additionally includes an assay pad (64, 66, 68, 70) in which the soluble analyte present in the fluid sample can.be assayed. A method of separating high-density lipoproteins (HDL) from low- and very-low-density lipoproteins (LDL and VLDL) employs a coated glass fiber matrix which inhibits binding of HDL as a blood fluid sample containing HDL and precipitated LDL and VLDL passes through the matrix.

Title: Baby stroller with removable wheels
Inventor: BAECHLER PHILIP A
IPC: B62B5/04
Filed: 1994-09-14
Granted: 2007-07-31
Abstract: An all terrain baby stroller using an axle assembly that allows the rear wheels to be easily and quickly mounted and removed from the stroller frame without tools. The axle assembly has each rear wheel rotatably mounted on an outward end portion of a stub axle. A tubular rear axle defines a cylindrical interior chamber with an outward end opening sized to slidably receive the stub axle inward end portion therethrough for positioning of the stub axle inward portion coaxially within the interior chamber. When so positioned, a circumferential groove of the stub axle inward end portion is positioned within the interior chamber. The tubular sidewall of the rear axle has an aperture positioned axially inward from the interior chamber outward opening and at a location to coincide with the circumferential groove. A lock pin is carried by a strip spring and is movably disposed in the sidewall aperture for selective movement between an engagement position and a disengagement position. In the engagement position the pin extends into the interior chamber and into the circumferential groove of the stub axle inward end portion to prevent axial withdrawal of the stub axle from the interior chamber. When in the disengagement position, the pin is sufficiently clear of the circumferential groove to permit the stub axle inward end portion to be axially inserted into and removed from the interior chamber.
