Title: Time domain reflectometer display method
Inventor: LANAN KEITH W
IPC: G01R31/11
Filed: 2000-12-06
Abstract: A computer-based method and computer-readable medium containing computer-executable instructions for assimilating data collected by a time domain reflectometer and displaying more than two waves representing reflections of a pulse on conductors is provided. The method includes a means for wave reversal, wave shifting, multi-wave display, segmented velocity of propagation adjustment, multi-cursor option multi-flagging options and calculating of the total length of wet cable. The combinations of these functions provides a highly accurate means for identifying the location of splices, faults, corrosion, cable damage and other anomalies that are typically found on any length of conductor cable. The ability of this method to display a greater number of waves simultaneously adds additional benefit to a technician attempting to locate particular anomalies with multi-conductor cables.

Patent CA-2399521-A1 (CA)
Inventor: DIEHL JASON K
IPC: A01K49/00
Filed: 2002-08-22
Abstract: An insect rearing tray is disclosed comprising a base member for containing insects, a cover member for covering the base member and engageable with the base member, providing a container having an upper surface, a lower surface and a peripheral wall, and vent openings in the peripheral wall sized to retain the insects within the container. As the peripheral wall incorporates vent openings, the need for ventilation is met even while trays are stacked for transport. Unlike the case with existing trays, producers can leave the cover member in place during the entire incubation process, as air circulation can occur and the structure is such that parasitoids are not discouraged from exiting the tray. If producers choose to leave the cover member on the incubation tray, the vent openings along the peripheral wall should allow air to pass closer to the surface of the bee cells inside. The preferred incorporation of additional vent openings in the upper surface of the container enables observation of the insects with the cover member in place, especially important when determining sex and quantifying the insects. Finally, removing the need for traditional aluminium mesh screens increases the structural strength, and the ability to solely employ injection-moulding manufacture in providing a ventilated container decreases manufacturing costs.

Abstract: A device for collecting pet feces before they reach the ground. The device is comprised of a waste disposal bag affixed to a pair of horizontal arms joined at one end to form a "V". The vertex of the V is affixed to an inclined handle that is sufficiently long to enable a standing operator to hold the V arms close to the ground. A  bag attachment fixture near each vertex of the triangle formed by the two V arms enables the mouth a common plastic bag to be held open to form a triangular disposal bag.  The user grasps the handle and holds the stretched triangular bag under the rear end of a defecating animal such that its feces fall directly into the bag for subsequent disposal.  In a preferred embodiment, each V arm is swingably affixed to the lower end of the handle by means of a hinge who's axis bisects the angle subtended between the plane of the V arms and the handle, thereby permitting each arm to fold flush against the handle for compact storage. The folding embodiment may also include either a telescopic handle or folding handle. A carrying hook or loop may also be provided for attaching the folded device to the handle of a pet leash.
