US Patent:

51573580, Oct 20, 1992

Filed:

Nov 20, 1991

Appl. No.:

7/795351

Inventors:

James A. Benson - Huntingdon Valley PA

Assignee:

Sonex Corporation - Philadelphia PA

International Classification:

H04L 2712

US Classification:

332100

Abstract:

A modulation circuit that is particularly suited for a communication modem and provides for each of the channels precise carrier mark and space frequencies generated in response to external signals from an FSK communication station. The modulation circuit includes first and second frequency controlling circuits arranged with an inductor to form a resonant circuit of a voltage variable oscillator. The modulation circuit further includes a feedback control network and a voltage-frequency control adjustment circuit. The feedback control network generates a loop error signal applied to both frequency controlling circuits. The voltage-frequency control adjustment circuit generates a voltage-frequency adjustment control signal and has a switching circuit responsive to the external signals. The voltage-frequency control adjustment circuit includes an inverting network and a bias network. The inverting network receives the loop error signal and provides, when in an operative state, an output signal that is phase shifted by a predetermined amount from the loop error signal.

Appl. No.:

6/364296

Inventors:

James A. Benson - Huntingdon Valley PA

Assignee:

Philmont Electronics, Inc. - Philadelphia PA

International Classification:

G08G 107

US Classification:

340912

Abstract:

A coordinator for a traffic signal controller having a motor and associated switching system for establishing the duty and width cycle of the controller. The controller being connected, via electrical circuitry, to an AC power grid. The coordinator is a self-contained unit arranged for connection to the controller to effect coordination thereof by producing timing signals in response to receipt of either AC signals from the electrical circuitry or stray AC radiation from adjacent sections of the power grid. The coordinator also includes an independent oscillator for producing independent timing signals. Thus, the coordinator can maintain coordination of the controller under normal operating conditions or under the abnormal operating conditions of a local power failure or a general power failure.

G06F 3/16

Abstract:

A medical/veterinary procedure simulation apparatus includes a simulated mammalian body part. The simulated mammalian body part further includes one or more anatomical replications of mammalian tissue. The apparatus also includes an attaching substrate for fixedly attaching the simulated body part to a mammal or a model of the mammal. The apparatus further includes one or more sensors configured to provide a quantified measurement of one or more actions, pertaining to at least one medical procedure. The apparatus further includes a virtual reality system configured to receive one or more input signals from the one or more sensors. The virtual reality system is further configured to display at least one visual representation of at least one clinical procedure being performed on the one or more anatomical replications based on the one or more input signals from the one or more sensors.
