A thermally actuated device, such as an electrical circuit breaker () is provided with an ambient temperature compensation thermostat metal member () selected so that it bends when subjected to changes in temperature and compensates for ambient temperature effects on a thermostat metal trip arm for a selected current rating. Movement of such thermostat metal member is directly proportional to the flexivity of the material and to the square of the length of the member and indirectly proportional to the thickness of the member. Since packaging constraints make changes in length impractical, compensation members used to provide temperature compensation for different current ratings of the device typically have been made by using members of different thickness. In accordance with the invention, ambient temperature compensation members for a family of devices having a plurality of different current ratings is provided by changing the effective length of respective blank thermal compensation members by stamping selected deformations () appropriate for each current rating in respective blank compensation members.

A shouldered connector pin socket () is shown having an open channel () formed in the face surface of a wall member of a circuit breaker housing. An electrically conductive spring member (′) is received over the channel and is formed with a first set of spring fingers () that are adapted to engage a connector pin along a first axial length () of the channel making electrical engagement with the pin and urging the pin against the channel surface as the pin is slidingly inserted into the channel. The spring fingers urge the flange of the connector pin into a recess formed by a stepped shoulder defining the entrance to a second axial length () with the stepped shoulder and the spring fingers cooperating to retain the connector pin in the channel. A second set of spring contact fingers () can also be used to engage the connector pin along a third axial length () and thereby provide a redundant contact system.

An apparatus includes a housing. A waveguide is located within the housing. The waveguide includes a first subsection that bends around a first axis and has a first cross-sectional area with an aspect ratio that is substantially different from unity. A second subsection bends around a second axis that is non-parallel to the first axis and includes a second cross-sectional area with an aspect ratio that is substantially different from unity. A third subsection acoustically couples the first subsection to the second subsection. The third subsection includes a third cross-sectional area with an aspect ration that varies between the first aspect ratio and the second aspect ratio.

An acoustic waveguide with at least two portions coupled by vibration damping structure. The vibration damping structure may be a conformable material such as closed cell foam. The vibration damping structure may further include structure for inhibiting motion in a direction transverse to the interface between the vibration damping structure and a portion of the waveguide.

A television includes a flat panel display device for presenting video images, a housing for supporting the flat panel display device, and a first acoustic volume located substantially (a) inside the housing, and (b) behind the display device. Two or more acoustic drivers are provided for acoustically energizing the acoustic volume. The drivers are positioned such that acoustic energy put into the acoustic volume from the drivers is substantially additive and vibrational energy from the drivers substantially cancels out.

An audio system includes a housing and an acoustic exit that exits the housing, and has a configuration that facilitates the grasping of the housing with a plurality of fingers from a single human hand. The acoustic exit is located adjacent an exterior surface of the housing such that the shape of the exit together with the exterior surface facilitates grasping of the housing with a plurality of fingers and the thumb from the single human hand and the acoustic exit exits a back surface of the housing such that the plurality of fingers can be inserted into the exit while the thumb of the same hand can rest on at least one of the top surface and the front surface of the housing.

An audio system has an enclosure and a transducer that is mounted to the enclosure. The transducer creates a vibration of the enclosure in response to being driven by an audio signal. A cradle assembly mechanically couples a portable device to the enclosure through one or more isolators such that only a portion of the vibration is coupled to the portable device. The enclosure is supported substantially entirely by the cradle assembly.
