摘要:
An apparatus comprises a thermal block (116) coupled to an electronic device (352), a thermal strap (102) coupled to the thermal block (116), and retention hardware (230) coupled to the thermal strap (102) and configured to retain the thermal block (116) within the thermal strap (102) when the apparatus is exposed to at least one variable environmental condition.
摘要:
A system (10) comprises a package (12) with top (22) and bottom (24) surfaces, a plurality of high-power transient voltage suppressors (15) arranged within the package, and a robust lead frame (16). Each of the transient voltage suppressors (15) has first and second major surfaces substantially perpendicular to the top (22) and bottom surfaces (24) of the package. The lead frame (16) comprises leads (18A,18B) connected to the major surfaces of the transient voltage suppressors. Each of the leads has a thickness greater than about 0.015 inches (0.381 mm) in a mounting portion (36), in order to dissipate heat from the transient voltage suppressors (15) and to resist vibration-induced stress on the package.
摘要:
A Full Authority Digital Electronic Controller (FADEC) has a stamped housing body (110), a FADEC circuit assembly (210) within the housing body, and a cover (120). An electrical connector (140) is mounted to the housing body.

摘要:
An electronic control configuration (10a) includes at least one secondary microprocessor (32a, 32b) operable to control a device (12). The at least one secondary microprocessor (32a, 32b) assumes protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector (18). The at least one secondary microprocessor (32a, 32b) assumes backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector (16). The backup control functionality of the at least one secondary microprocessor (32a, 32b) can be selectively disabled.
