Patent CA-2335275-C (CA)
Inventor: LAWRENCE CHRISTOPHER G
IPC: H04B1/707

Granted: 2005-11-15
Abstract: The present invention relates to a wireless communication system in which a base station selects its own operating channel from a multiplicity of permissible channels. One or more other channels in addition to the operating channel are selected as backup channels. The base station provides information on the selection of backup channels with remotes of the base station. When the base station is required to change its operating channel, the base station moves to the first backup channel, with the second backup channel becoming the new first backup, and so on. The selection of both operating and backup channels are based on a single numeric interference score for each permissible operating channel. The base station contacts a central administration facility when the number of frequencies that meet a given selection criterion falls below a predetermined threshold.

Granted: 2006-08-01
Abstract: A binding arrangement and a process for the control of a binding arrangement is described that includes a binding material delivery arrangement, a cutting arrangement and a braking arrangement for the binding material, where the brake can be controlled and generates a variable braking force. To improve the binding process for harvested crop, brakes for the binding material are applied with which a binding material tension is generated or is increased to cause the binding material to be retarded during the binding process in opposition to the flow of the binding material. The brakes are controlled such that only a low binding material tension is caused at the beginning of the binding process to increase the tension to as large a value as possible during the continuing binding process and to reduce the tension upstream of the cutting arrangement again at the end of the binding process.  This control is done through a control arrangement, as a function of the binding material delivery conditions, and performs at least two changes in braking force within one binding cycle.

Title: High citrate dialysate and uses thereof
Inventor: CALLAN ROBIN
IPC: A61K33/00
Filed: 2000-09-22
Granted: 2009-03-03
Abstract: The dose of dialysis in terms of urea clearance is marginal in many hemodialysis patients, and metabolic acidosis as determined by the pre-dialysis serum HCO3 level is common. A dialysate that included citric acid rather than acetic acid as acidifying agent provides superior performance properties. Citrate-containing dialysate was used exclusively in 22 hemodialysis patients. Initially, only 8 of the 22 patients had a pre-dialysis serum HCO3>23mEq/L (lower limit of normal), however, after 12 weeks of dialysis using the citrate-containing dialysate, the serum HCO3 normalized in 15 patients (p=0.0001, Chi-square). Dialysis variables were kept constant in 19 of the patients, who also used and reused the same dialyzer model throughout. In these patients, the initial average urea reduction ratio (URR) was 68.5.plusmn.5.9%, and after treatment with the citrate dialysate disclosed herein, this ratio had increased to 73.plusmn.5.3% (p<0.03). SpKt/V, calculated using the Daugirdas II formula, also increased from 1.23.plusmnØ19 to 1.34.plusmnØ2 (p=0.01). This increased urea clearance may be the result of the anticoagulant property of citrate maintaining patency of the dialyzer membrane. The increase in pre-dialysis serum HCO3 may represent increased delivery from the dialysate and production from citric acid.
