Patent CA-2340989-A1 (CA)
Inventor: MATTISSON SVEN
IPC: H04B1/713
Filed: 1999-09-14
Abstract: Transmission power in a frequency-hopping radio system that transmits packet s from a sending radio unit to a receiving radio unit, wherein each packet includes an address designating the receiving radio unit, is controlled by measuring received signal strength of packets whose addresses were successfully received in the receiving radio unit, regardless of whether oth er portions of the respective packets were successfully received. An average signal strength value is generated from the received signal strength measurements. The mathematical difference between the average signal strengt h value and a target value associated with the receiving radio unit is then determined and used as a basis for deciding whether to send a power control message from the receiving radio unit to the sending radio unit. In order to  provide a hysteresis in the power control process, a power control message i s sent from the receiving radio unit to the sending radio unit if the mathematical difference is greater than a first decision boundary, or if the  mathematical difference is less than a second decision boundary. The power control message may itself include the mathematical difference which, when received by the sending radio unit, is used as a basis for determining a transmission power level adjustment amount.The target value, against which the average signal strength value is compared, may be based on the receiver sensitivity adjusted to account for implementation losses and other inaccuracies.

Title: Livestock watering method and apparatus
Inventor: ANDERSON JAMES H
IPC: A01K7/02
Filed: 2001-08-31
Abstract: The freezeless method for watering livestock, in one embodiment, is a method and means to provide water to livestock using a well, trough and a piston pump that is activated and powered by the animal. The animal uses its nose to push a plate on a lever apparatus that is attached to the pump. The pushing motion causes a rod to move the piston pump, which in turn raises water to the surface via piping into the trough where the animal drinks the water. The animal continues to pump the lever apparatus until the desired amount of water is consumed. By using a drain means and insulation means, the apparatus operates in freezing temperatures without the use of a power or heat source.

IPC: G01M3/32
Filed: 1990-01-23
Abstract: The present invention relates to a method and apparatus for reducing the test cycle time and for improving the measuring accuracy of a leak testing process of a container. The process comprises the steps of providing a pressure difference as an initial predetermined pressure between the exterior of a closed container and the interior of the closed container without destroying the integrity of the container. The pressure exterior to the sealed container is measured for a certain time. This measurement determines the pressure integrity of the closed container. The method also includes the step of minimizing the volume of the exterior of the closed container wherein the size of that volume determines the test cycle tame and the measuring accuracy. The invention further comprises a test chamber which is closable and contains a cavity for introducing the container under test. A means is provided for installing or introducing a pressure difference at an initial predetermined value between the exterior of the container under test and the interior of the cavity. A measuring unit is provided for measuring the pressure value which is dependent on the pressure difference and the leakage of the container. The shape of the cavity is at least substantially geometrically similar to the shape of the container so as to minimize the volume of the cavity outside the sealed container under test.
