39478343, Mar 30, 1976

Filed:

Apr 30, 1974

Appl. No.:

5/465677

Inventors:

David N. Gershberg - Rockville MD
Alex Y. Lee - Arlington VA
Clair F. Parker - Fairfax VA

Assignee:

E-Systems, Inc. - Dallas TX

International Classification:

G08B 1318

US Classification:

340258A

Abstract:

A flexible line distributed antenna, defining a perimeter of interest, radiates energy supplied from a transceiver. Motion around the flexible line causes the reflected energy which is intercepted by the flexible distributed antenna to be coupled back to the transceiver as a doppler frequency for processing in an alarm system. Reflected energy from the antenna to the transceiver is amplified and rectified into a DC voltage. This DC voltage is integrated to produce a time varying signal to a level detector that responds to a predetermined value of the integrated DC voltage. A response by the level detector provides an actuating signal to an alarm indicator through alarm logic. Ambient conditions around the extended flexible line distributed antenna are monitored by external sensors having outputs for controlling amplifier gain and triggering the alarm logic. For improved motion detection reliability, reflected energy from the antenna is coupled to a transceiver providing two output signals. These two output signals are processed separately for coupling to a voltage comparator driving an alarm indicator through alarm logic.

Bruce E. Johnson - Bellevue WA, US

International Classification:

H04L 12/911
G06F 9/50
H04L 29/08
H04L 12/24

Abstract:

An intelligent placement engine generates a placement map that provides a configuration for deploying a service based at least in part, on one or more configuration parameters. A data center in which the service is to be hosted is defined using a data center definition, while the service is defined using a service definition. The configuration parameters include estimated probabilities calculated based on estimated resource consumption data. The resource consumption data is estimated based at least in part on historical data distributions.
