Patent CA-2265599-A1 (CA)
Inventor: DEMAREST SCOTT W
IPC: A01M1/02
Filed: 1997-09-18
Abstract: A bait station for crawling insects and method for presenting bait to targeted insects. The bait station (10) includes a base (12) and a cover fastened to the base. The base (12) includes a bait cup (16) with a bait cup wall. A side support extends upwardly above the level of the bait cup wall. The cover (14) includes a shell (30) that defines a walkway (34) between the shell wall (32) and the bait cup wall (20). The shell (30) also includes a roof (40) that spans the space encompassed by the shell wall (32), the roof (40) being supportable by the side support. An antechamber is defined on one side by the side support and on another side by the shell wall. The floor of the antechamber is continuous with the floor of the walkway. An antechamber door in the shell wall opens into the antechamber to admit targeted insects thereto and is so located that straight line access through the antechamber door to the bait cup is restricted by the side support. The antechamber is sufficiently wide from the side support to the shell wall as to provide room for a targeted insect to enter the bait station through the antechamber door and avoid the side support by entering the walkway, thus gaining access to any bait contained in the bait cup. The method of the invention includes providing such a bait station, containing a selected bait within the bait cup and placing the bait station on a surface where targeted insects crawl.

Title: Short pulse mid-infrared laser source for surgery
Inventor: HOFFMAN HANNAH J
IPC: H01S3/16
Filed: 1998-01-28
Abstract: A solid state laser source for surgical applications is disclosed which produces short-pulse, mid-infrared radiation. Specifically, the laser preferably emits radiation near the absorption peak of water, with energy levels up to 20 mJ, pulse durations shorter than 50 ns and preferably shorter than 30 ns, with beam quality of less than 8 times the diffraction limit. The short pulses reduce unwanted thermal effects and changes in adjacent tissue to potentially sub-micron levels. The laser source produces pulse repetition rates in excess of 10 Hz when pumped by a flashlamp, but in a diode pumped embodiment, the repetition rate may exceed 30 Hz. Of particular interest is an erbium-doped YAG laser which is especially well suited to the needs of midinfrared corneal ablation procedures for correcting refractive errors, when constructed according to principles disclosed by the invention.

Title: Method of mapping fibre channel frames based on control and type header fields
Inventor: FIACCO PETER
IPC: G06F13/14
Filed: 1999-04-26
Abstract: A method and apparatus for processing and transferring frames of data in a computer link that maps incoming frames to a specific buffer ring in host memory (312) based on routing control and type fields in each frame. More particularly, a Fibre Channel link port (302) contains receiver routing code (RRCode) registers (400) that allow host software to set up routing control (R_CTL) match and mask fields, and TYPE match and mask fields. The link port uses these registers to match and mask against corresponding R_CTL/TYPE fields in a received frame to determine which of several R_CTL/TYPE host memory buffer rings should be used to store the received frame. The link port places a code (RRCode) in a start of frame (SOF) status word associated with a frame.  The RRCode indicates a specific R_CTL/TYPE host memory buffer ring, or indicates that no match was found or that multiple matches were found. A  protocol engine (306) reads the RRCode field in the SOF status word of the received frame, and queues a direct memory access (DMA) operation to an appropriate R_CTL/TYPE buffer ring. The host may then process the contents of the indicated buffer ring. Since the buffer rings are "pre-sorted" as to frame type, the host may more efficiently respond to incoming frames.
