Patent CA-2236530-C (CA)
Inventor: BODIE CAM
IPC: A01D69/03
Filed: 1998-05-01
Granted: 2008-03-18
Abstract: This invention pertains to hydraulic systems for agricultural implements whereby two or more fluid power sources are combined in parallel. Total fluid capacity is increased so that one source may have reserve capacity for serving other loads. Flow controls for the system are set so that one source maintains at least a minimum flow to a load when the flow provided by the other source diminishes. Specifically, an aircart fan is operated by fluid power combined from a tractor source and a ground driven pump source with controls being provided to control the fan speed and proportions of flow from each source. The ground driven source (boost pump) boosts available fluid power volume to meet demands of the aircart fan. The boost pump is located near the aircart fan and connected with short lines to minimize power loss in the lines. The boost system shares the tractor components for fluid reservoir, filtering, and cooling so that it does not require its own such components.

Title: System for deferred call answering in a telecommunications system
Inventor: OTTO MARY RITA
IPC: H04M3/487
Filed: 1998-08-10
Granted: 2001-09-11
Abstract: The called party can temporarily defer answering a call simply by pressing a button on the station set. When the button is pressed, the called party's station set sends a data message to the system's voice response unit directing the voice response to play a "please wait" message to the calling party rather than sending the calling party to the called party's voice mail. The voice response unit plays the "please wait" message to the calling party and sends a call park message to the switching system hosting the station set. The call park message to the switching  system directs the switching system to park the call at a specific location as is known in the art and a corresponding call park message to the station set transmits the location of the parked call to the station set. When the called party desires to answer the call, a message is sent from the station set to the switching system requesting that the call parked at the identified location be connected to the station set. The call can then be connected without the existing call being interrupted and the third party knowing of its existence.

Abstract: A wavelength-variable light source apparatus having a wavelength measurement function for measuring the wavelength characteristic of an object to be measured. In the apparatus, a CPU outputs control signals for controlling components of a light power meter section via a bus for controlling a light detection operation. When the CPU obtains light detection level data detected by the light power meter section from light passing through an object to be measured, the CPU stores the light detection level data for each wavelength in the object to be measured in an RAM and causes a display control section to display the light detection level on a display section. Further, the CPU executes wavelength analysis processing according to a wavelength analysis program stored in an ROM, analyzes the light wavelength characteristic of the object to be measured based on the light detection level data for each wavelength stored in the RAM, and causes the display control section to display the analysis result on the display section.

Abstract: Reading disorders are diagnosed and remediated in a subject by respectively measuring and improving contrast sensitivity for motion discrimination of the subject. A background (130) is displayed on a monitor (104) with a contrast and a spatial frequency. A test window (134) is superimposed over the background (130) and includes a test pattern (132) with a contrast and a spatial frequency. The contrasts and the spatial frequencies are within respective ranges which simulate the visual cortical movement system of the subject. The test pattern (132) is then moved within the test window (134). The subject provides a signal indicative of the direction of the subject believes the test pattern (132) moved. In response to this signal, the contrast of the test pattern (132), the spatial frequency of the background (130), or the spatial frequency of the test pattern (132) is modified, either by increasin g or decreasing its respective value. This process is then repeated a number of times, cycling through predetermined combinations of test patter ns (132) and backgrounds (130). Contrast sensitivity may be measured to determine whether a child is dyslexic. Repeated stimulation by t he methods and apparatus of the invention improves contrast sensitivity, thereby remediating dyslexia and improving reading ability.</SD OAB>

Granted: 2008-02-05
Abstract: This invention relates to methods of initiating a reconfiguration of a cell regarding the number of signalling channels in relation to the number of traffic channels. Each signalling channel (SDCCH/8) contains a number of dedicated control channels (SDCCH). The invention can be divided into two parts, an increase condition in which a traffic channel (TCH) is converted to a signalling channel (SDCCH/8) and a decrease condition in which a signalling channel is reconverted to a traffic channel. These two conditions can be performed independently of each other. In the increase condition, the conversion to a signalling channel is done based on three conditions (1, 2, 3; Fig 3) depending on the number of idle dedicated channels (SDCCH) and the number of traffic channels (TCH).  In the decrease condition, the conversion (Fig 4; Fig 5) is based on the number of signalling channels (SDCCH/8) and the dedicated control channels (SDCCH) in the cell.
