Title: Method and apparatus for controlling electronic signs using radiopaging signals
Inventor: DABBS JAMES M III
IPC: G08B5/22
Filed: 1993-07-21
Abstract: An advanced telecommunication system is provided for central control of electronic signs (32). A display development kit is provided to create binary display programs which create visual activity on one or more electronic signs. These display programs are stored on the disk drive (18) of a system control computer (16) which periodically runs a system control program to upload display programs to the electronic signs using radiopaging signals. The system control program employs a telephone modem (20) to connect through a public switched telephone network (PSTN) (26) to a paging terminal (22). In accordance with the system control program, the system control computer divides each display program into multiple packets which are transmitted to the paging terminal as alphanumeric radiopages. The paging terminal encodes the packets into radiopaging format, frequency shift key modulates the data, and transmits the pages on a radio frequency channel.  Electronic signs (32) decode the radiopages into data packets. A receiver subsystem (34) in the electronic sign reconstructs the original display programs using the data packets. Data provided in a display program can span across more than one page. The system control program creates packets containing display program data such that blocks of display program data that are greater than one page are transmitted transparently to a paging terminal from the central computer, and from the paging terminal to a paging receiver without requiring hardward or sof-tware modification of existing paging terminals and paging central offices.
Patent CA-2143920-A1 (CA)
Inventor: CZERMAK KARL
IPC: C21B13/06
Filed: 1995-03-03
Abstract: There is disclosed a method of charging fine-grained ore into a reactor pressure vessel through which process gas flows. The heated ore at first is introduced into a conveying pressure vessel, is pressurized within the same by compressed gas and subsequently is conveyed into the reactor pressure vessel through a conveying duct by aid of thecompressed gas. In order to ensure favorable utilization of the reactor pressure vessel under uniform stress and to safeguard troublefree progression of reduction while directly charging the ore, a portion of the ore is introduced into at least one further conveying pressure vessel and is pressurized within the same also by compressed gas. Charging of the ore into the reactor pressure vessel is effected continuously by alternately feeding once from the one conveying pressure vessel and subsequently from the other conveying pressure vessel. The compressed gas is taken from the process gas as a quantitative or as a component portion of the process gas and is fed back to the same along with the ore.

Patent CA-2147029-A1 (CA)
Inventor: BRULE PHILIP JAMES
IPC: B62J9/00
Filed: 1995-05-03
Abstract: This invention relates to a compartmentalized travel bag that easily converts from panier form (for cycling) to an internal frame packsack (for walking or hiking). The apparatus is composed of three separate compartments that share a common backing which is stiffened in such a way as to allow it to bend at two joints (or hinges) forming an inverted "U" shape, (like a panier), as well as straighten and form an internal frame packsack. There are two shoulder straps and a belt attached to the backing, (for use while in packsack form) which can loop around and fasten to the outside of the bag while in panier form. There are fasteners on the outside of the bag that work in combination with the stiffened backing to keep the bag straight while in packsack form. This invention enables the cyclist to participate in other activities such as hicking, canoeing or mountain climbing, without having to carry aditional equipment during a cycle trip. Also, since both hands are free while the Panpack is in packsack form, it allows the cyclist to easily maneuver the bicycle and gear while in train stations or airports.

IPC: G06F13/00
Filed: 1993-12-07
Abstract: A complex system, e.g. a telecommunications network, is monitored for fault conditions. In order to correlate the alarms to establish which alarms (e.g. 31, 32, 33) have a common cause, a logical connectivity  model is used in which a logical property is transferred  between related logical elements (e.g. 41, 52) in response to the element (41) being alarmed. If as a result of such transfer the value of the logical property exceeds a threshold value for any element (61) a correlation is established and the element (61) highlighted (72) as the probable cause of the alarms.

Title: Method for preparation and transplantation of volute grafts and surgical instrument therefor
Inventor: HUGHES STEPHEN E
IPC: A61B17/00
Filed: 1993-09-10
Abstract: A method of transplant-ing a graft in the subretinal area of a host eye comprises prepar-ing the graft by harvesting from the donor tissue a population of cells in a manner that main-tains the population of cells in the same organization and cel-lular polarity as is present in normal tissue of that type. The population of cells are of a sheet-like from and are assem-bled with a relatively thin flex-ible pliable carrier composed of a non-toxic flexible compo-sition which substantially dis-solves at body temperature to form a graft. The graft is suf-ficiently flexible and pliable to be coiled to form a volute (76) without disturbing the organi-zation and polarity of the cells. The method further comprises coiling the graft to form a vo-lute (76) with the convolutions of the volute (76) free of one another for subsequent uncoiling of the graft substantially to its original sheet-like form. An incision is made in the host eye for insertion of the volute (76). The incision in the eye is smaller than the incision that would be required for insertion of the graft in its uncoiled sheet-like form.  The volute is inserted one end first into the host eye through the incision and transported to a position between the retina and the underlying tissue. The volute (76) uncoils after its insertion to lie in sheet-like form between the retina and underlying tissue of the host eye. The incision is then closed.

Filed: 1995-10-23
Abstract: A system is provided to control operation of an implantable medical device basedupon detected EMI (electromagnetic interference). A correlator produces a correlation function indicating the level of an EMI component of an input biomedical signal that includes a biomedical signal component and an EMI component, and that is monitored relative to a predetermined threshold to allow the device to operate in a normal manner as long as the intensity or level of the EMI component is such that it does not affect or interfere with device operation. One or more remedial measures may be selected in the event the level of the EMI component exceeds a predetermined threshold. The system is useful with any electronic device which receives an electronic information signal which may include an EMI component.

Abstract: Steerable tag axle assemblies include an axle mounting lever carrying a wheel on a stub axle and either a kingpin pivot or a spherical bearing pivot for laterally turning the wheel.  The lever pivots between a stowed position and a deployed position where lateral forces from the ground urge the wheel to follow the vehicle.  In one embodiment, a kingpin pivot connects the stub axle to the lever and a tie rod maintains alignment of the pair of stub axles.  In another embodiment, a kingpin pivot connects the lever to a pivoting shaft attached to the vehicle.  The shaft turns as  the  lever  moves  between  the  deployed  and  stowed positions, and the lever pivots laterally at the kingpin pivot  to turn the wheels.    In  another  embodiment,  a spherical bearing is carried by a spherical bearing mount securely attached to the vehicle.  The bearing engages the lever in a bearing cavity,  such that the lever pivots laterally and between the stowed and deployed positions on the bearing.  Lateral movement of the wheel is limited in each embodiment.
