US Patent:

51949865, Mar 16, 1993

Filed:

Mar 23, 1992

Appl. No.:

7/856429

Inventors:

James J. Carlson - Woodland Hills CA
Gary R. Noyes - Los Angeles CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

G02B 1314
G02B 2304

US Classification:

359353

Abstract:

A portable missile launcher has an optical system with a single lens (22) for receiving visible and near infrared light energy from a target (14) directing it to a prism (24) where the light is split into a part transmitted to an eyepiece (28) and a further part (30) to infrared tracking equipment (18). The objective lens (22) is a doublet having a front lens (32) and a rear lens (41) which cooperate to provide sufficiently small chormatic aberration to enable image quality correction for both visual examination and near infrared tracking.

Appl. No.:

7/855974

Inventors:

James J. Carlson - Woodland Hills CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

F41G 700

US Classification:

244 311

Abstract:

A portable missile launcher (12) has all of the infrared tracker (20) mounted to the same housing (48). The infrared missile beacon image beam (26) is intercepted by a rotating prism (28) which directs a portion of the beam to a narrow field detector (32) and reflects a further portion from a coating (30) onto a wide field detector (34). The detectors (32,34) provide yaw and pitch signals (40,42) which are compared with on-course information producing error signals communicated to the missile for course correction, if needed.

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

G02B 110
G02B 528
G02B 1314

US Classification:

359356

Abstract:

An optical system (10) for portable missile launcher (23) includes an objective lens (12) for receiving the entire visual and near infrared light energy emanating from a target (14) and immediate background of the target. The light energy from the objective lens then passes through a Porro prism assembly (16) which acts to direct visual light along a first path to an eyepiece (20) and near infrared along a second path at approximately a right angle to the first path where it is received by a tracker assembly (22) and monitored. The Porro prism (16) is constructed in accordance with this invention to include a multi-layer interference dichroic coating (18) disposed between the two prisms (34,36) which make up the prism assembly. This coating is of such a nature as to readily permit light energy in the visual range to pass directly through the coating, but at the same time to reflect the near infrared components along a second path bringing them to focus on the tracker assembly (22).

International Classification:

A61B 504

US Classification:

128702

Abstract:

A method and apparatus for automatic rhythm analysis of digitized ECG signals. Candidate heartbeats are detected and the noise of the ECG signal portion containing the candidate is evaluated to determine whether the candidate is a valid nominal or noisy beat or an invalid noisy saturated signal. The timing of detected heartbeats, both noisy and nominal, are determined relative to prior validated heartbeats. Features of the detected heartbeats are automatically extracted including onset, offset and R wave locations; QRS complex width; R-R interval based on the onset points; instantaneous and averaged heartrates; and others. A 16 point template of the heartbeat starting at the onset is also determined. Beats are then classified in a two step process; first, by template comparison with a previously determined dominant template, and second, by a finite state machine process based on the results of the template comparison and relative timing of the beat. As a result of the two step classification beats are classified as belonging to a plurality of beat types including both single and sequence beat types.
