Title: Method for detecting addressing errors in an electrical unit
Inventor: BARTHEL HERBERT
IPC: G06F11/16
Filed: 1994-05-09
Abstract: ABSTRACT OF THE DISCLOSURE   The present invention provides a method for detecting addressing errors in an electrical unit. The electrical unit may, e.g., include a central processing unit and modules that respond to the central processing unit via a communication system by means of addresses specific to the modules. Addressing errors caused by faulty modules can be detected. For at least a portion of the accesses made by the central processing unit on one of the modules, an identifier is transmitted from the addressed module to the central processing unit. The identifier transmitted to the central processing unit is compared to a reference identifier. Addressing errors are recognized when the transmitted identifier deviates from the reference identifier.

Inventor: JIN XIXUAN
IPC: A01N63/30
Filed: 1993-05-27
Abstract: Methods for packaging Metarhizium fungal cultures or conidia are described. In one embodiment, the fungal culture is provided within an insect infection chamber that attracts insects, then infects them with a lethal dosage of fungus, where the packaging maintains high humidity within the chamber, allows free exchange of gases, and is impermeable to microbes, including fungal spores, viruses, and bacteria. In a second embodiment, the fungal conidia are packaged under conditions which maintain high viability even after long-term storage at both 25 ·C and 37 ·C, i.e., low relative humidity and oxygen.

Abstract: Coreless paper roll products are formed by slitting a paper web to form web segments having side edges. The web segments are then wound about an elongated winder shaft.  During winding of the paper web, liquid is applied to the web segments only at the side edges thereof while maintaining the web segments free of liquid between the side edges. A  rider roll that has liquid applied thereto by sponges or spray nozzles may apply liquid to the side edges of the web segments. When the rolls are formed and stripped from the winder shaft, the openings located at the ends of the roll at the roll central aperture will be well defined and allow ready insertion of a dispenser spindle. All the material of the roll can then be dispensed.

Filed: 1995-09-29
Abstract: A direct digital frequency synthesizer for generating a digital. sine or cosine function waveform includes input means to receive digital input. Memory stores digital samples along portions of sine and cosine function waveforms. The memory outputs the digital samples in response to a first portion of the digital input. Control logic responsive to the input means controls the output of the digital samples from the memory to allow digital samples along a complete cycle of the sine or cosine function waveform to be output even though only portions of the sine and cosine function waveforms are stored in the memory. Linear interpolation means receives a second portion of the digital input and modifies digital samples output by the memory to generate intermediate digital samples between the digital samples stored in the memory to improve accuracy.

Abstract: A compact diversity antenna is presented consisting of two electrically isolated orthogonal loop conductors joined at a midpoint. This midpoint is also electrically attached to a vertical conductor which produces a third mode of operation electrically isolated from the first modes . The two horizontal conductors and the vertical conductor may be constructed to have various relationships with a ground plane of various shapes and sizes. Some of the possible feed arrangements for each of the antennas is presented as well as matching and tuning circuits. All three antenna elements are found to have relatively weak near electric and magnetic fields on the ground plane side of the antenna where the ground plane is small in extent. This feature provides for reduced radiation into the head and neck of the cellular phone user.

Inventor: COOPER RANDALL L
IPC: B08B3/00
Filed: 1996-03-14
Abstract: An automatic dishwashing machine includes enhanced drying and draining cycles.  Toward the end of the rinse and hold cycle when the water is draining, a second quantity of water is added to the machine resulting in a purging action which reduces the concentration of soil in the wash pump.  During the normal wash cycle, if the dishwashing machine determines that the water is sufficiently dirty, a second drain is initiated to remove any dirty water that is present in the bottom of the pump after the first drain.  During the dry cycle, the machine senses the temperature of the water and the presence of a rinse aid to select an appropriate dry cycle.  The possible dry cycles include a delayed dry cycle and a pulsed dry cycle.
