Patent CA-2111680-A1 (CA)
Inventor: BARRETT DAVID M
IPC: G06F1/04
Filed: 1992-05-26
Abstract: 2111680 9306545 PCTABS00021 In a portable computer, a device driver program causes the system to conserve power whenever the processor is idle. The program detects the idle processor via a unique interrupt generated by the operating system's idle loop. After detecting the idle state, the program conserves power usage by slowing the system clock speed and halting the processor. The system returns to its normal operating state when the processor detects an external interrupt.  Although an operator action generates an external interrupt, the 55 ms periodic timer typically awakens the processor. In addition, the program blocks the power saving measures in cases where the operator would notice performance degradation.

Title: Method of and apparatus for canceling electric field
Inventor: ONODERA TOSHIO
IPC: H04N9/29
Filed: 1993-12-23
Abstract: ABSTRACT OF THE DISCLOSURE         An electric field cancellation apparatus that can reduce electric field radiation from a cathode ray tube inexpensively includes a canceling pulse generating circuit generating a pulse voltage that cancels a leaked electric field radiated from a high voltage generating circuit employed with a deflection circuit or the like.  The canceling pulse voltage is superimposed upon an output voltage of the high voltage generating circuit and is applied through an anode to an aperture grill of the cathode ray tube, whereby an electric field having a phase opposite to that of the leaked electric field is radiated from the whole surface of the aperture grill, so that the leaked electric field radiated from the cathode ray tube can be canceled.

Title: Coating process and apparatus
Inventor: BAYER GLEN H JR
IPC: B05C1/06
Filed: 1994-04-25
Abstract: ABSTRACT OF THE DISCLOSURE The invention includes a method and apparatus for applying a single or multiple layer coating material to a substrate using a generally cylindrical application roller. First and second coating materials are extruded and join together to form a multiple layer coating material. Additional layers may be similarly provided if desired. The multiple layer coating material may then be transferred on the peripheral surface of the application roller to a substrate, such as paper. The application roller may be rotated to produce a surface velocity that is greater than the velocity of the extruded multiple layer coating material, to draw the material and provide a thin multiple coating layer. Furthermore, the substrate may be conveyed past the application interface at a velocity greater than the surface velocity of the application roller, to provide further drawing of the multiple layer coating material.

Title: Methods for in situ construction of deep soil-cement structures
Inventor: KONO IKUO
IPC: E02D5/18
Filed: 1994-09-22
Abstract: METHODS FOR IN SITU CONSTRUCTION OF DEEP          SOIL-CEMENT STRUCTURES             ABSTRACT OF THE INVENTION     Methods are provided for the constructing of subterranean soil-cement structures in situ. The methods utilize techniques designed to prolong the period of time in which an auger machine can operate in a bore hole without encountering difficulty due to the hardening of the soil-cement mixture. The techniques utilized include a preparatory drilling phase during which a lubricating slurry may be injected. This preparatory drilling serves to break up the soil and particularly if a lubricating slurry isused, reduce friction so that final drilling may progress more quickly. After preparatory drilling, final drilling takes place. Final drilling is divided into a downward and an upward phase. Either hardening or non-hardening slurry may be introduced and consolidated with the soil during the downward phase, but only hardening slurry is typically utilized during the upward phase of final drilling. These techniques result in a quicker and more homogenous mixture of slurry and soil and allow the bore hole to be deeper.

Patent CA-2136154-A1 (CA)
Inventor: BENAYON JAY W
IPC: G06F9/50
Filed: 1994-11-18
Abstract: The present invention provides the user with the ability to control and administer the supply of memory managed in multiple heaps by a library heap management facility. The control data used by the heap management facility is located in the user-supplied memory. Heaps are created dynamically through calls from the application to the runtime library. Allocation within a heap is performed through calls to the runtime library that canvass the available heap memory for each allocation request. If no suitable block of heap memory is located, additional user supplied memory is requested for the application through a callback function. A second callback function notifies the user when a supplied unit of memory is no longer required by the heap and may he disposed of. The callback functions are specified separately for each heap. The invention also provides the user with means for setting the default heap in the runtime library for use by allocation requests from a vendor library that do not specify a heap. This can be done on a per thread basis in multithreaded applications so that different executing threads can use different default heaps in a non-interfering manner.

Title: Actuator with translational and rotational control
Inventor: NEFF EDWARD A
IPC: B25J11/00
Filed: 1995-01-16
Abstract: An apparatus for precisely moving and positioning a manufacturing component  includes  a housing on which a magnet is mounted.  An electrical coil is wound around a coil piston which is slidingly mounted on the housing for movement within the magnetic field generated by the magnet. A rod,  having a member for gripping the component,  is attached for translational movement with the coil piston, and a source of electrical current is connected to the coil which is wrapped around the coil piston.   A pneumatic rotary actuator is mounted on the apparatus, and a coupling connects the rotary actuator to the grip for rotation of the grip as desired.  A vacuum source can be connected to the grip to allow picking up a fragile workpiece.  In the operation of the apparatus, a current is selectively passed through the coil.  This current in the coil then moves the coil piston and the attached grip within the magnetic field to position the component as desired in translation.  Also, the rotary actuator can be activated to move the grip in rotation as desired.  Additionally, position sensors can be mounted on the apparatus to determine the location of the coil piston, and a controller can be incorporated in the apparatus  to  use  this  position  determination  for controlling movement of the coil piston and the attached grip in translation and rotation.

Title: Technique for use in processing telephone calls
Inventor: EISDORFER JERRY
IPC: H04Q3/66
Filed: 1995-10-10
Abstract: A telecommunications carrier other than the carrier of last contact is arranged to a) recognize that the telephone to which a particular call is placed is a disconnected telephone and b) provide different call treatment for the call, e.g., different call handling or different call features or services, as compared to the treatment the telecommunications carrier provides for the same call to the same telephone when it is recognized that the telephone is not disconnected. Advantageously, no effort is wasted in an attempt to complete the telephone call to a disconnected telephone. Such different treatments include 1) simply making no attempt to route the call to the disconnected telephone via the network of last contact, 2) routing the call to a secondary, alternate telephone, and 3) initiating transmission of a page to a pager that is associated with the owner of the disconnected telephone.
