US Classification:

248660, 2482741, 2481841, 248550, 248637, 396 12, 396 13

Abstract:

A gimbal system. The gimbal system may include space-saving features configured to accommodate one or more payload components, thus increasing the payload capacity of the gimbal ball without necessarily increasing the outer dimensions of the gimbal ball. Alternatively, or in addition, the gimbal system may include a motor configured to move at least one gimbal relative to another gimbal about a first axis, with the motor peripherally mounted distal the axis.

International Classification:

G02B 23/00

US Classification:

359421

Abstract:

Optical systems, including apparatus and methods, for obtaining images, particularly with multiple fields of view. These systems may utilize a plurality of optical components with different optical axes, where the optical axes may be selectively rotated into alignment with an imaging axis to obtain images having various discrete fields of view.

John M. Wiltse - Lake Oswego OR, US

Assignee:

FLIR Systems, Inc. - Wilsonville OR

International Classification:

G02B 7/182

US Classification:

359871

Abstract:

A spatially efficient kinematic mirror mount for mounting a mirror or other optical element to a housing. The kinematic mirror mount may include three spaced-apart constraint structures, positioned at or near the outer perimeter or circumference of the mirror. The constraint structures constrain the mirror to lie within a plane, typically the x-y plane defined by the orientation of the housing, substantially without overconstraining the mirror. To accomplish this, each of the three constraint structures may constrain the mirror in the x-y plane by independently providing a tangential constraint to the mirror. The constraint structures may include a tab, coupled to the mirror by a flexure, and a fastening assembly for securing the tab to the housing.

International Classification:

B41J 2938
B41J 2045

US Classification:

347 11

Abstract:

An apparatus and method provide on-demand drop volume modulation by utilizing a single transducer driving waveform to drive an ink jet. The driving waveform includes at least a first portion and a second portion that each excites a different modal resonance of ink in an ink jet orifice to produce ink drops having different volumes. A control signal is applied to the driving waveform to actuate the selected portion of the waveform to eject the desired ink drop volume for a given pixel. The control signal also cancels the non-selected portion(s) of the waveform to avoid extraneous excitation of the transducer.

Appl. No.:

7/622716

Inventors:

Ari Glezer - Tucson AZ
Kris J. Nygaard - Glendale AZ
John M. Wiltse - Tucson AZ

International Classification:

F15C 104

US Classification:

137 13

Abstract:

Substantial alteration of the flow conditions in a fluid stream are effected by the application of controlled disturbances to the boundary of or within the stream by one or more piezoelectric actuators. The actuators have resonance frequencies substantially in excess of the unstable frequencies of the stream. The actuators are energized by carrier signals at the resonance frequencies of the actuators, which carrier signals have been modulated at the desired unstable frequency of the stream.

International Classification:

B05B 1706

US Classification:

239 4

Abstract:

Synthetic jet actuator, which can be micromachined if desired, generates a synthetic jet stream characterized by a series of successive vortices that can be used for effectively entraining adjacent fluid. The synthetic jet actuator can be used to bend, or vector, a jet stream from another jet actuator. Further, because the synthetic jet actuator exhibits zero net mass flux, the synthetic jet actuator can be used within a bounded volume. In structure, the synthetic jet actuator comprises a housing defining an internal chamber and having an orifice. A flexible metallized diaphragm forms a wall of the housing and can change the volume of the chamber when moved. An electrode is disposed adjacent to and spaced from the diaphragm, and an electrical bias is imposed between the metallized diaphragm and the electrode by a control system to force movement of the diaphragm. As the diaphragm moves, the volume in the internal chamber changes and vortices are ejected from the chamber through the orifice.
