Assignee:

Passif Semiconductor Corp. - San Mateo CA

International Classification:

H04R 5/02
H04R 5/00

US Classification:

381 23, 381307

Abstract:

A wireless multi-channel audio system including an audio source with a wireless transceiver configured to communicate according to a standard wireless protocol and an audio controller, which are collectively configured to establish wireless communications with multiple audio sinks via a corresponding wireless link, to assign each audio sink a corresponding audio channel, to synchronize timing with each audio sink, and to transmit audio information for each audio channel to a corresponding audio sink via a corresponding wireless link. The audio source may inquire as to supported audio parameters, such as sample rate and audio codec, and selects a commonly supported configuration. The audio source may separate audio information into queues for each audio channel for each audio sink. The audio source transmits frames with timestamps and a common start time for synchronization, and the audio sinks use this information to synchronize timing and remain virtually synchronized with each other.

Spectra-Physics, Inc. - San Jose CA

International Classification:

H01S 308

US Classification:

372 99

Abstract:

A wavelength selective mirror provides single wavelength operation of a gas laser. In a specific embodiment an output coupler optical interference coating allows oscillation of the 488. 0 nanometer line of the Argon ion laser blue/green spectrum while suppressing all other lines in that spectrum, particularly adjacent lines at 476. 5 nanometers and 496. 5 nanometers.

Appl. No.:

7/603128

Inventors:

Benjamin H. Cook - Livermore CA
William P. Kolb - Redwood City CA

Assignee:

Coherent, Inc. - Palo Alto CA

International Classification:

H01S 322

US Classification:

372 59

Abstract:

A gas laser includes a housing containing a lasing gas. Means are provided for electrically exciting the gas including a cathode mounted at one end of the housing and an anode mounted at the other end. The temperature of the anode is monitored and a control signal is generated which is indicative of the temperature that is measured. An automatic gas supply apparatus is activated to vary the gas pressure in the housing in response to the control signal. Additionally, the temperature that is measured may be normalized to counteract the effects of the ambient temperature of the anode.

International Classification:

H01S 303

US Classification:

372 61

Abstract:

A sealed laser plasma tube for use in a gas laser system. A Brewster window seals one end of the tube (the cathode end, in a preferred embodiment), and an end mirror which seals the opposite tube end (the anode end, in a preferred embodiment). In a laser system embodying the invention, a second end mirror is positioned adjacent to, but spaced from, the Brewster window. Intra-cavity elements may conveniently be inserted and replaced in the region between the sealed Brewster window and the second end mirror. The sealed mirror which seals the tube end opposite the window is preferably coated with at least an outermost layer of Hafnium oxide, to protect it from hard UV radiation originating within the plasma tube. The inventors have recognized that the problem of sealed window degradation is substantially less severe at the cathode end of an ion laser plasma tube, and that the sealed window should be attached at the tube end at which the window degradation problem is less severe.

Benjamin H. Cook - Livermore CA

Assignee:

Coherent, Inc. - Palo Alto CA

International Classification:

H01S 308

US Classification:

372 99

Abstract:

An improved laser mirror (22) is disclosed with wavelength selective coatings on the inner and outer surfaces (32) and (34) thereof. The coating on the inner surface (32) is reflective of light in a first wavelength region (36) and transmissive of light in a second wavelength region (38). The outer surface (34) is reflective of light in the second wavelength region ( 38). In the preferred embodiment, one of the surfaces of the mirror is planar and the other is curved to facilitate alignment. The different curvatures of the inner and outer surfaces allows the diameter of the beam of the two wavelength regions to be independently controlled allowing optimization of the mode generated by the laser (20).

Inventors:

- Dallas TX, US
Benjamin Stassen Cook - Los Gatos CA, US
Sebastian Meier - Muenchen, DE

International Classification:

H01L 21/762

Abstract:

A device includes a die with a protective overcoat and a substrate, the substrate comprising a first region and a second region that are spaced apart. The device also includes an isolation dielectric between the protective overcoat and the die. A pre-metal dielectric (PMD) barrier is between the isolation dielectric and the substrate, the PMD barrier having a first region that contacts the first region of the substrate and a second region that contacts the second region of the substrate, the first region and the second region of the PMD barrier being spaced apart. A through trench filled with a polymer dielectric extends between the first region and the second region of the substrate, and between the first region and the second region of the PMD barrier to contact the isolation dielectric.

Abstract:

A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.
