Title: Light sensitive control for toaster
Inventor: TRAN DUC HOANG
IPC: A47J37/08
Filed: 1997-07-24
Abstract: In  a  toaster,  a  system  is  constructed  to  vary  the duration of the toasting cycle.  An RC network provides an  oscillating  signal to  a  counter,  which  upon  the required number of oscillations being counted, triggers a transistor  switch.    The  switch  energizes  the  main solenoid switch which in turn deactivates  the heating elements of the toaster.   The RC network of the system comprises  a variable   resistor which may be manually operated,  a  heat  sensitive  resistor,   and  a  light sensitive resistor.

Inventor: JONES WILLIAM J
IPC: G07D7/00
Filed: 1995-03-08
Abstract: A currency counting and discrimination device for receiving a stack of currency bills, rapidly counting and discriminating the bills in the stack, and then re-stacking the bills. The device comprises an input receptacle for receiving a stack of currency bills to be discriminated, a denomination-discriminating unit for discriminating the denomination of the currency bills, an output receptacle for receiving the currency bills after being discriminated by the discriminating unit, and a transport mechanism for transporting the currency bills, one at a time, from the input receptacle past the discriminating unit and to the output receptacle. The transport mechanism comprises means for stripping the lowermost bill from a stack of bills in the input receptacle, first and second driven transport rolls on opposite sides of the discriminating unit for transporting each bill past the discriminating unit, and to the output receptacle along a transport path. In a preferred embodiment, a stripping wheel is rotatably mounted about an axis, the stripping wheel having a high-friction surface or a raised surface along only a portion of its circumference such that during rotation of the stripping wheel that portion intermittently engages the lowermost bill of the stack of bills. Means are provided for ensuring that when the stripping wheel is stopped, that high-friction and/or raised surface portion of its circumference is not engaging the lowermost bill.

Title: A method and apparatus for limiting access to a nonvolatile memory device
Inventor: AIYAR SANJAY
IPC: G06F1/00
Filed: 1996-04-25
Abstract: A method and apparatus for limiting access to a nonvolatile memory device (50) by inserting access limiting circuitry (74, 80; 60, 62) between CPU generated read (OE#) and write (WE#) command signals being sent to the nonvolatile memory device (50) and the nonvolatile memory device itself such that write commands can be received and executed by the nonvolatile memory device (50) only when the CPU is in a System Management Mode, and such that read commands for protected addresses can be received and executed by the nonvolatile memory device (50) only when the CPU is in the System Management Mode, but is still able to receive and execute read commands for non-protected addresses regardless of the mode of the CPU. This feature can also be provided for the write command. The access limiting circuitry (74, 80; 60, 62) is therefore capable of preventing a virus program, or a malfunctioning operating system, from undesirably altering data in the nonvolatile memory device (50) since the operating system is preempted when the CPU is in the System Management Mode.

Title: Method of inspecting cornering control mechanism of vehicle
Inventor: MAEKAWA KEIICHIRO
IPC: G01M17/06
Filed: 1998-07-10
Abstract: While a vehicle is running on a bench type of testing apparatus for inspecting a cornering control mechanism, the connection of one of drums on which one of the left and right driving wheels is mounted is released from the other drums. Then, the rotational speed of said one of the driving wheels increases and the rotational speed of the other of the driving wheels decreases. At this time, a controller mounted on the vehicle judges that the vehicle is in an oversteering state, and the brake of said one of the driving wheels is switched on (or operated). Then, based on the deceleration of said one of the driving wheels, a discrimination is made as to whether the cornering control mechanism has operated normally or not. Since the rotational speed of said one of the driving wheels decreases also when an accelerator is switched off (or pressing down of the accelerator pedal is released), a discrimination is made based on the deceleration of the other of the driving wheels as to whether the accelerator is switched off or not. When a discrimination is made that the accelerator has been switched off, the discrimination of operation of the cornering control mechanism based on the deceleration of said one of the driving wheels is prohibited.
