Title: Clock recovery circuit with memory storage level comparison with high, medium and low thresholds
Inventor: YAMADA HIROKI
IPC: H04N1/21
Filed: 1992-03-27
Abstract: A coded image signal is received and stored into a first-in-first-out memory on a bit-parallel word basis and the storage level of the memory is compared with high, medium and low threshold values. A first positive trimming value is generated when the storage level is higher than the high threshold, a second positive trimming value when it lies between the high and medium thresholds, a first negative trimming value when it is lower than the low threshold, and a second negative trimming value when it lies between the low and medium thresholds. Differential sampling clock data is received and combined with each trimming value in an adder whose output is subtractively combined with a frequency variation of the line clock rate to produce a corrected differential sampling and line clock data. The latter is integrated to produce a frequency control signal that drives a voltage-controlled oscillator whose output is used to drive the memory for reading the coded image signal on a bit-parallel word basis.

IPC: F42B12/54
Filed: 1992-12-30
Abstract: A remote injection device for animals comprises a barrel with a piston slidable within the barrel from an initial retracted position at one end of the barrel forwardly toward the opposed end of the barrel to discharge liquid in an injection action through a needle at the forward end of the barrel. The piston is held in a retracted position by an O-ring on a release member which projects through an O-ring carried on the inside surface of the barrel. The inner diameter of the O-ring on the barrel can be adjusted by axial movement of the pair collars on the inside of the barrel. This adjusts the amount of force necessary to push the release member O-=ring thorugh the outer O-ring to release the piston to be moved by spring to the discharge position. The barrel can be mounted either upon an arrow type projectile so the impact forces are sufficient to release the piston upon engaging the animal. Alternatively the barrel can be mounted upon a pole with the pole acting to release the piston when pushed forwardly with the needle and barrel in engagement with the animal.
