Patent CA-2295805-A1 (CA)
Title: Multi-function control handle
Inventor: BERGMAN BRENT A
IPC: G05G9/04
Filed: 1998-07-20
Abstract: A handle (35) mounted generally horizontally on a fork lift truck for controlling forward and reverse speed of movement of the truck and raising and lowering forks is carried by a control device (100). The control device includes a shaft (150) with a centrally positioned spherical section (160) contained in a socket (172, 176) in a support member (170).      The shaft is therefore free to rotate about the center (177) of the sphere. A ramp cam (200) is mounted on the support member surrounding the shaft. A slider (180) mounted on the shaft is pressed against the cam by action of a spring (190). This action rangement assures that the shaft and control handle remain centered until acted upon by an operator of the truck. Two linear potentiometers (270, 290) provide electrical output signals representing the X (horizontal) and Y (vertical) positions of the end of the shaft opposite the control handle. The cam is provided with four distinct compound surfaces (201-204). For vertical movement of the handle, the slopes of the two lower surfaces (202, 203) are greater than the slopes of the two upper surfaces (201, 204). The slopes of each surface are also different in the forward and reverse direction. This arrangement provides the illusion that the same force is required to move the handle in any direction. A decent (215) in the center of the cam requires a slightly greater force to move the handle from the center position.

Title: Method for detecting contamination and/or damaging of a face that runs through a nip or nips in a calender for paper
Inventor: SUOMI EERO
IPC: G01H1/00
Filed: 1998-11-03
Abstract: The invention concerns a method for detecting contamination and/or damaging of a face (10) that runs through a nip or nips (N1...N10) in a calender for paper. In the method vibrations occurring in connection with the constructions (18, 100) of a calender are detected and processed. The vibrations are detected by means of at least one vibration detector (40; 41...46; 41a...46a, 41b...46b) fitted in connection with the bearing supports of calender rolls (11...16) or in connection with constructions (18, 100) related to said bearing supports. By means of these vibration detectors the calender roll(s) (11...16) is/are identified from which the vibration derives. In the method, it is possible to observe the rotation of all of the rolls to be monitored and to measure vibration from any suitable point whatsoever, for example from the frame (100) of the machine, by employing at least one vibration detector (40), the time (T r) of the cycle of the vibration signal obtained from said detector(s) being compared with the numbers of revolutions of the rolls to be monitored. In this way, the source of the disturbance is determined, and action is taken in order to eliminate the disturbance.

Patent CA-2311368-A1 (CA)
Inventor: DESGAGNE MICHEL
IPC: H04W72/08
Filed: 1998-11-20
Abstract: Each base station in a cellular telephone system includes a signal strength measurement device operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed against the measured uplink interference for those frequencies having more than a threshold number of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment at either call set-up or hand-off from the least (adjusted) interfered frequency.

Title: Communication system for mobile devices
Inventor: HIROSE NORIHIKO
IPC: H04W16/26
Filed: 1999-12-24
Abstract: The present invention has the purpose of providing technology capable of efficiently transmitting data when performing data communications between a mobile station and a server apparatus. A simplified protocol TL is employed on the transport layer instead of TCP/IP. The simplified protocol TL is used as the communication protocol on a wireless communication path (radio-oriented interval) between an MS (Mobile Station) 1 and a GWS (GateWay Server) 5. The simplified TL protocol is utilized to relay data communications between the MS 1 and a CPS 8 (Content Provider Server). The response of data communications is therefore improved by a decrease in traffic between the MS 1 and the GWS 5 and reduction in overhead in comparison to when TCP/IP is deployed. As a result, the user can efficiently access content provided by the CPS 8 over the Internet via a wireless communication path. Efficient access may occur even where the wireless communication path has low data transmission capacity in comparison to a wireline communication path. In addition, efficient access may occur where the user is using an MS 1 which has insufficient data processing power to deploy TCP/IP.

IPC: E04H4/12
Filed: 2000-10-25
Abstract: A floating skimmer is provided for use with a pool cleaner of the type powered by a suction or vacuum source, such as by connecting the pool cleaner via a vacuum hose or the like to the suction side of conventional pool water filtration equipment, wherein the floating skimmer is coupled along the vacuum hose and functions to collect debris picked up by the pool cleaner as well as floating debris such as leaves and the like on the pool water surface. The floating skimmer comprises a buoyant housing having a perforated collection basket therein defining a primary debris collection chamber adapted for in-line connection along the vacuum hose to capture debris entrained with water drawn from the suction-powered pool cleaner to the filtration system. The perforated basket additionally defines a secondary debris collection chamber for capturing floating surface debris drawn over at least one weir, with a flow control valve assembly regulating the weir surface flow to insure that a sufficient flow is drawn through the pool cleaner for proper pool cleaner operation. A water level regulator float responds to the water level within the skimmer housing to variably open and close submerged auxiliary intake ports therein to maintain the water level generally between predetermined maximum and minimum limits. The collection basket is mounted within the buoyant housing for quick and easy removal as needed to dispose of collected debris.

Abstract: Apparatus and method is provided for integrating cellular communications with a portable computer for off-loading processor and display intensive functions onto the greater capabilities of the computer. In one embodiment, a cellular transceiver is computer-based. A small wireless telephonic handset interfaces with the computer and cellular transceiver. The computer is used to actuate the cellular transceiver through its input interface or through voice activation. Preferably the handset is incorporated into a data-input stylus for the computer. The computer enables incorporation of encryption/decryption between the handset and computer and voice recognition. The computer can further incorporate a database list and program for storing and receiving phone numbers and thereby actuate the cellular transceiver. The list can be accessed through the computer interface, or through voice recognition through the handset. In another embodiment the cellular transceiver is located in the handset but employs only elementary input/selection functions and minimum energy storage, minimizing the handset's size by relying on the computer's interface for selecting phone lists and synchronizing computer and handset lists and its and power cell for frequent recharging.
