Title: Processor with data format-independent instructions
Inventor: CORCORAN GARY T
IPC: G06F9/312
Filed: 1991-02-21
Granted: 1996-08-13
Abstract: A processor specially adapted for use as a coprocessor. The processor is implemented as a microprocessor. The adaptations include the following: The microprocessor has a master-slave pin which receives an input which determines whether the microprocessor operates as a bus master or a bus slave. Certain output pins have three-state bus drivers which employ feedback to ensure that a signal on a line being driven by the driver has gone inactive before the driver is turned off. Instructions executed by the microprocessor permit specification of portions of the internal registers as sources and destinations and specification of the size of an ALU operation, permitting easy operation on data ranging from bytes through 24-bit pointers. Instructions are executed in an instruction pipeline and a separate I/O instruction pipeline. Some pipeline stalls are avoided by means of a special MOVE instruction which differs from an ordinary MOVE instruction in that it does not cause pipeline stall when it reads data from a register loaded by a preceding READ instruction. The microprocessor also has an Intel/Motorola pin whose input specifies the type of host processor the coprocessor is working with and further executes I/O instructions which permit the same code to be used with either host processor.

Patent CA-2038952-C (CA)
Title: Packet/fast packet switch for voice and data
Inventor: BUCHHOLZ DALE R
IPC: H04L12/64
Filed: 1990-08-23
Granted: 1998-02-03
Abstract: An improved network interface architecture for a packet/fast packet switch is described. This network interface architecture provides for the combination of both voice and data in a single switch using a common packet structure. It allows for the dynamic allocation of bandwidth based on system loading. This includes not only bandwidth within the voice or data areas of the frame, but also between the voice and data portions. The network interface (NI) provides a means (the NI-Bus) of passing all packets through the Network interface or allowing the packet devices to directly transfer packets between one another. The bandwidth allocation can easily be changed because the control and data memories are synchronized to one another. The network interface architecture, according to the invention, allows for the data packets and the control of bandwidth allocation to be controlled by a single switching device. It synchronizes the transfer of the data and the allocation of bus bandwidth. The control of the packet devices can be controlled at a very high bit rate such as, for example, 40 Mbps. It also allows packet devices to directly transfer packets. It allows for easy re-allocation of bandwidth, through the use of the NI Base Registers.

Title: Thermally activated vent damper
Inventor: KARABIN TADEUSZ
IPC: F23L13/02
Filed: 1991-07-08
Granted: 1996-11-12
Abstract: A thermally activated vent damper assembly  for a flue is adapted to be situated in relation to the flue for occluding the passage of gas through the flue.  A support member traverses the flue and suspends the damper member across the flue for movement between an open and a closed position.    A  thermally  activated  biasing  member  is operatively  coupled  between the  support member and the damper  member  to  bias  the  damper  member  in  the  open position in the presence of heat and to bias the damper member in the closed position in the absence of heat.  The coupling of the biasing member between the support member and the damper member is such that potential sites for frictional  inhibition  of  damper  member  movement  are eliminated.  Upon breakage or other failure of the biasing member to apply bias,  the damper member defaults to or remains in an open position under the force of gravity, providing for a unique fail-safe feature.

Title: Expanded porphyrins: large prophyrin-like tripyrroledimethine-derived macrocycles
Inventor: SESSLER JONATHAN L
IPC: C07F3/08
Filed: 1990-03-06
Granted: 2004-07-13
Abstract: The present invention involves a novel tripyrroledimethine-derived "expanded porphyrin" (texaphyrin), the synthesis of such compounds, their analogs or derivatives and their uses. These expanded porphyrin-like macrocycles are efficient chelators of divalent an trivalent metal ions. Metal complexes of these compounds are active as photosensitizers for the generation of singlet oxygen and thus potentially for inactivation or destruction of human immunodeficiency virus (HIV-1), mononuclear or other cells infected with such virus and tumor cells as well. A variety of texaphyrin derivatives have been produced and many more are readily obtainable. Various metal (e.g., transition, main group, and lanthanide) complexes with the texaphyrin and texaphyrin derivatives of the present invention have unusual water solubility and stability which render them particularly useful. These metallotexaphyrin complexes have optical properties making them unique as compared to existing porphyrin-like or other macrocycles. For example, they absorb light strongly in a physiologically important region (i.e. 690-880 nm). These complexes also form long-lived triplet states in high yield and act as efficient photosensitizers for the formation of singlet oxygen. These properties, coupled with their high chemical stability and appreciable solubility in polar media such as water add to their usefulness.

Title: Crawling and talking doll
Inventor: FERRI JAIME
IPC: A63H3/28
Filed: 1991-08-07
Granted: 2003-11-25
Abstract: The doll of the invention incorporates a mechanism and electric circuit that, originating from a general activa-tion motor which moves a series of engagements, brings about a correlative series of movements which cause the doll to crawl and give out a message and, subsequently, to stop crawling and raise the trunk of its body and head, to turn its head and give out a new message. These movements are based on the eccentric operating several elements related to the arms, legs and head. Likewise, the emission of the messages is based on parts which are independent but combined electrically and mechanically with the general mechanism in order that, altogether, they achieve a succesion of movements which are repeated constantly until a general switch is activated by means of, for example, a dummy, or by means of a ball switch activated automatically when the doll is picked up and put upright.

Filed: 1991-09-04
Granted: 1996-09-10
Abstract: An efficient digital beam-forming network (100) utilizing a relatively few small-scale A/D converters is disclosed herein. The inventive beam-forming network (100) is disposed to generate an output beam B in response to a set of N input signals. The set of input signals is provided by an antenna array (110) having N elements, upon which is incident an electromagnetic wavefront of a first carrier frequency. The present invention includes an orthogonal encoder circuit (170) for generating a set of N orthogonal voltage waveforms. A set of biphase modulators (162-168) modulates the phase of each of the input signals in response to one of the orthogonal voltage waveforms, thereby generating a set of N phase modulated input signals. The N phase modulated input signals are combined within an adder (180) to form a composite input signal. The inventive network (100) further includes a downconverting mixer (184) for generating an IF input signal in response to the composite input signal. The IF input signal is then separated into baseband in-phase and quadrature-phase components by an I/Q split network 192. A pair of A/D converters (198, 200) then sample the in-phase and quadrature-phase components of the input signal. A decoder (202), coupled to the orthogonal encoder circuit (170), provides decoded digital in-phase signals and decoded digital quadrature phase signals in response to the digital in-phase and quadrature-phase signals. The present invention further includes a digital beam-former (130) for generating the output beam B by utilizing the decoded in-phase and quadrature-phase signals.
