Abstract: A cooking oven and method of cooking vertically arrayed food carrying skewers movably attached and carried in a horizontal endless travel path by conveyor means to encircle a heating element array within a single open cooking oven chamber so as to constantly directly and indirectly expose the food to the heat radiated from the element array throughout the complete travel path within the oven chamber. A plurality of internested drip pans are disposed within the oven chamber vertically beneath the food travel path for collecting juice drippage. The oven chamber superposed beneath a conveyor chamber contains an alternating array of infrared gas burners and reflectors arranged upright in a row. A slot communicating between the conveyor chamber and oven chamber provides for travel of suspended food carrying skewers within the oven chamber and incorporates a gasket seal to retain heat and inhibit transfer of contaminants downwardly to the oven chamber.

Abstract: The present invention provides a method and apparatus for detecting voltage drops on an IC chip. The device operates by using a reference voltage to detect the voltage range of a local voltage. A multiple number of reference voltages are used (or predetermined) between the reference voltage and the ground voltage. The voltage drop detecting device includes a multiple number of inverters having to the local voltage as its input. The inverters each have a trigger voltage corresponding to one of the reference positions. When the local voltage is smaller than the trigger voltage of the inverter, a low to high voltage switching is present at the output. A multiple number of positive-edge triggering devices, coupled to the reference voltage as one of its inputs, are each coupled to one of the inverters. A corresponding inverter presents a low to high switching to make the reference voltage present at the corresponding output terminal. The voltage range of the local voltage is detected at the output terminals.

Abstract: An apparatus for use in a computer software protection system includes a protection device and a key externally connected thereto. The key includes a resistor and capacitor connected in series. The protection device includes an I/O port connected to the key such that a charge on the capacitor corresponds to a voltage on the I/O port. The I/O port is connected, selectively to ground by an NMOS switch, which is controlled by a control signal from a control program executing on a main game machine. The protection device further includes a voltage comparator having an input connected to the I/O port, and an output connected to an I/O interface that interfaces the protection device to the game console. In operation, the control program determines whether the key has a valid charging characteristic, as determined by the selection of the resistor and capacitor. While the control signal is unasserted, the NMOS switch is off, and the capacitors fully charged through the resistor.

Abstract: An image register for a graphics display includes a pair of static random access memory (SRAM) devices for respectively storing image data associated with even numbered and odd numbered pixels, which correspond to even numbered and odd numbered addresses. The register includes a counter presettable to an initial value corresponding to a starting address of the stored image data. When the counter outputs an even address (an even state), the even SRAM is enabled for a write operation if an input layer code has a higher priority than the priority of the layer code for the image data stored in the even SRAM, although the odd SRAM is always enabled for a read operation in the even state. The read and write operations occur simultaneously. During the read operation on the odd SRAM, the layer code portion of the image data retrieved therefrom is latched in an associated buffer, whose output is fed to an associated comparator.
