International Classification:

F24F 13/12

US Classification:

454334, 454228, 454261, 454333, 454358, 454259, 236 491, 236 495

Abstract:

An HVAC unit ventilator, particularly suited for schools and hotels, includes a single damper blade driven directly by a motor to control a supply air's mixture of return air and outside air. The damper blade is selectively pivotal to a full outside air position, a full return air position, and various intermediate mixed-air positions. The damper blade has flexible edge and end seals that create little if any frictional drag as the damper blade pivots to the intermediate positions, yet the seals provide a positive, tight seal when the damper stops at either the full outside air position or the full return air position. The unit ventilator includes a filter frame that not only supports an air filter but also provides the damper blade with sealing surfaces and structural support. For rigidity, the damper blade has somewhat of a box-like structure that is bi-directionally reinforced by ribs and triangular gussets.

International Classification:

H04K 1/10

US Classification:

375260

Abstract:

A system for detection and avoidance of victim services in ultra-wideband (UWB) systems is provided. A detect and avoid module may calculate power averages of Orthogonal Frequency Division Multiplexing tones. The power of tones may be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The UWB subsystem may be configured with known bands of victim services of other radio frequency systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.

US Classification:

375260, 375296, 375299, 375346, 375347, 375348, 375349

Abstract:

A method, system, and computer-readable medium for detecting an interferer in a wireless communication system are provided. The method includes receiving a signal having P tones, each of the P tones being associated with a frequency, determining a first signal quality of each of the P tones, determining a second signal quality of each of the P tones, and detecting the interferer that occupies the same frequency as one of the P tones based on the respective first signal quality and the respective second signal quality. The first signal quality and second signal quality behave differently when the interferer is present. The detecting the interferer includes determining a discrepancy in the behavior of the first signal quality and the second signal quality.

Inventors:

Syed Masood Ahmed - Canton MI, US

International Classification:

B42D 15/00

US Classification:

283 80

Abstract:

An identification tag is provided that includes an elongate strip of flexible material having a top surface, a bottom surface, a first end and a second end. The identification tag further includes adhesive material and a label, the label being configured such that information may be added thereto. The strip of flexible material may be configured to wrap around about itself to produce a generally circular shape.

International Classification:

H04N 7/15
H05K 7/00

US Classification:

348 1408, 36167901

Abstract:

One embodiment is an enhanced power supply including electronic power supply circuitry within a housing. The enhanced power supply further includes one or more sockets operatively associated with the housing providing for the connection of an external apparatus to the enhanced power supply such that the external apparatus may communicate data or another signal through the connection to an output cable. The output cable may to be connected to a device such that both power and at least one signal will be provided to the device through the output cable. Systems featuring an enhanced power supply and methods of providing power and one or more other signals to a device with a reduced number of cables are also disclosed.

International Classification:

H04L 122

US Classification:

370217

Abstract:

A method of accomplishing switchover from an inservice local to a remote NP (Network Processor) is described. The remote NP is periodically updated with configuration data obtained from the inservice local NP. Switchover from the local inservice NP to the remote NP is initiated. Communications between the remote NP and a plurality of NEs (Network Elements) is established nonsynchronously. The local NP is notified that the remote NP is established as an inservice NP.
