Abstract:

A multi-beam electron gun provides a plurality N of cathode assemblies comprising a cathode, anode, and focus electrode, each cathode assembly having a local cathode axis and also a central cathode point defined by the intersection of the local cathode axis with the emitting surface of the cathode. Each cathode is arranged with its central point positioned in a plane orthogonal to a device central axis, with each cathode central point an equal distance from the device axis and with an included angle of 360/N between each cathode central point. The local axis of each cathode has a cathode divergence angle with respect to the central axis which is set such that the diverging magnetic field from a solenoidal coil is less than 5 degrees with respect to the projection of the local cathode axis onto a cathode reference plane formed by the device axis and the central cathode point, and the local axis of each cathode is also set such that the angle formed between the cathode reference plane and the local cathode axis results in minimum spiraling in the path of the electron beams in a homogenous magnetic field region of the solenoidal field generator.

Appl. No.:

7/808084

Eric Malmberg - Santa Cruz CA

Zbigniew Siemiatkowski - Watsonville CA

Assignee:

Allen-Bradley Company, Inc. - Milwaukee WI

International Classification:

G01S 1380

US Classification:

342 44

Abstract:

A system for indenitfying objects, such as workpieces on an assembly line, includes a transponder for attaching to an object and a radio frequency (RF) transceiver. The transceiver can program the transponder with data about the specific object and interrogate the transponder to obtain previously programmed data. The transponder responds to different RF signal strengths and commands from the transceiver to select whether it will store or transmit data. Data is exchanged between the two devices using Manchester encoding. The transceiver processes the encoded data signal from the transponder by measuring and storing the intervals between level transitions in the signal. The stored intervals are then processed in non-real time to recover the data.

International Classification:

H04Q 700

US Classification:

34082519

Abstract:

A tongue activated communications controller for use by disabled or other persons to control a wide variety of devices, and which includes a dental appliance fitted to the user's palate, and a keyboard with a plurality of tongue activatable switches for generating a signal depending upon which switch has been selected, and upon the status of a battery voltage level. The communications controller includes a radio frequency transmitter which uses magnetic flux linkage for transmitting the signal. The communications controller further includes a receiver for converting the transmitted signal into digital form, and also includes a micro-processor based controller unit for processing the received data, and for communicating with the attached devices which the user wishes to control. Data is sent from the transmitter using a fixed transmission time, digital pulse code modulation technique to achieve ultra low power consumption in the transmitter. The controller unit processes the encoded data signal from the receiver by measuring and storing the intervals between level transitions, and then by processing these intervals in non-real time.
