Patent CA-2279466-A1 (CA)
Inventor: PALLAI LASZLO ANTAL
IPC: H01R4/48
Filed: 1999-07-30
Abstract: A screwless-type terminal block comprising a housing, a clamping member in the housing, a PCB conductive pin, and an actuating member. The housing defines a first opening for receiving therein a wire end and a second opening through which extends the actuating member which has a operating knob outside of the housing and a cammed end adapted to displace the clamping member between locked and unlocked positions thereof respectively for securing the wire end in an electrically conductive manner with the PCB pin and for allowing the wire end to be inserted in or withdrawn from the housing. When rotated, the operating knob causes the cammed end to rotate about a longitudinal axis of the actuating member such that the cammed end causes the clamping member to selectively displace between the locked and unlocked positions. The cammed end includes a flat surface angled with respect to the longitudinal axis and contacting the clamping member which displaces along a plane parallel to this longitudinal axis. The clamping is spring loaded such as to be biased towards the PCB pin. The operating knob and the housing are provided with visible indicators to indicate if the clamping member is in its locked or unlocked position. The terminal block is nestable in a side-by-side relationship with other similar terminal blocks.

Title: Length adjustable bottomrail for venetian type blind
Inventor: JUDKINS REN
IPC: E06B9/326
Filed: 1999-12-16
Abstract: A venetian type blind has a length adjustable bottomrail to fit windows of different lengths. A cord stop device is attached to each lift cord and each cord stop device is shaped such that when the device is attached to a lift cord the cord stop device can be removably connected to a retainer in the bottomrail and when not connected to the retainer will orient itself to be self guiding through route holes in selected slats when the lift cord is pulled through the selected slats. The blind is shortened by releasing each cord stop device from its retainer and passing the device and attached lift cord from the bottomrail through the slats to be removed to the slat at the desired length.  The excess slats are removed. Then the ladders are detached from the bottomrail, shortened and reattached to the bottomrail. The cord stop devices are then reconnected to their respective retainers in the bottomrail to complete the shortening process.

Title: Method and apparatus for analyzing an ultrasonic image of a carcass
Inventor: LIU YUJUN
IPC: G01S7/539
Filed: 2000-02-03
Abstract: The present disclosure teaches a system for analyzing ultrasonic image that provides an output of a measurement of muscle width from an ultrasonic image input of an outline of a muscle from an animal or carcass. The muscle that is used in the preferred embodiment is the longissimus dorsi muscle when an ultrasonic scan is taken in a transverse direction relative to the backbone. The analysis is done with a computer that receives the electronic input of rows and columns of gray level pixel data from an ultrasonic scan image of the outline of the muscle of the animal or carcass.  The software is set to select a region of the ultrasonic image input to analyze to determine a first edge of the muscle. The selected region is divided into subregions Sj.K. J designates a row and ranges between 1 and n. K designates a column and ranges between 1 and o such that o is greater than I. The subregions are aligned in rows and columns throughout the ultrasonic image input. The software calculates a sum of the gray level pixel data for each of the subregions Sj,k then compares the sums to determine which of the subregions Sj,k has the highest sum within each row j. The software defines a position of the first edge of the muscle by comparing the highest sum within each row j. This position is then used to calculate a relative muscle width when compared to a defined second edge of the muscle. The second edge can be defined as one edge of the selected region of the ultrasonic image input or it can be defined using the same steps used to define the first edge.
