摘要:
An enclosure for integrated circuit devices is disclosed. The enclosure includes a first portion which substantially encloses a plurality of secondary, relatively low-power integrated circuit devices and which includes a mechanism for contacting the secondary integrated circuit devices in order to conduct heat away. The enclosure also includes a second portion, which may include an active cooling device, directly in contact with a primary, relatively high-power primary integrated circuit device. In addition to removing heat, the first and second enclosure portions together shield the integrated circuit devices to contain electromagnetic energy generated by the devices. The first and second enclosure portions also allow different levels of force to be applied to the primary and secondary devices.

In one embodiment, an encoder reads a set of data from memory cells to obtain retrieved data influenced by one or more distortion mechanisms as a result of having been stored. A quality metric is generated responsive to the retrieved data that changes in value responsive to differences between the user data and the associated retrieved data. A quality monitor establishes a relationship between a current value of the quality metric and a threshold value and monitors the relationship as being indicative of a degradation of the quality of the retrieved data, and selectively initiates an error response. In another embodiment, a correction value is iterated through a set of values as a quality metric is monitored such that the value of the quality metric which most closely approaches the value of the quality metric immediately subsequent to an initial writing of the data can be selected.

Monitoring of a golf ball and apparatus for doing so is described using differential time locating. Launch parameters of a golf ball can be characterized independent of any specific positional measurement on the basis of a ball signal that is transmitted from the ball. These parameters include initial spin, initial velocity, and initial trajectory. Ground proximity detection is described as well as a landing position and rollout position detection technique and associated apparatus. Calibration techniques are described for various kinds of range receivers that subsequently receive the ball signal.

A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources. The at least one lighting device includes at least one lighting source, and an internal power source applying a first electrical current to illuminate the at least one lighting element, wherein the internal power source supplies the first electrical current. The at least one connector electrically connects to the at least one lighting device. The plurality of external power sources include at least first and second external power sources that are adapted to be electrically connected to the at least one lighting device by the at least one connector. The first external power source supplies a second electrical current to the at least one lighting device to illuminate the at least one lighting source and the second external power source supplies a third electrical current to illuminate the at least one lighting source, such that the internal power source and one of the plurality of external power sources each supply electrical current to illuminate the at least one lighting source at different times.

A cooling device primarily for cooling, e.g., integrated circuits or other electronic devices during operation may include a heat sink portion having a plurality of cooling vanes and a heat pipe chamber. Both the cooling vanes and the heat pipe chamber may be integrally formed within the heat sink portion. Because the heat pipe chamber is integrally formed with the cooling vanes, no joints exist between the condensing surface of the heat pipe chamber and the cooling vanes. This, in turn, allows extremely rapid and efficient heat transfer between the heat pipe chamber and the cooling vanes. The cooling device may include extensions of the main heat pipe chamber which project into each of the cooling vanes. In this manner, the condensing surface of the heat pipe chamber is actually moved into the vanes at a position very close to the surface of the vanes where heat transfer into the atmosphere occurs.

A removably mounted fan for an active heat sink, and the mounting of that combination to a part to be cooled, is obtained by: (1) The use a fan that engages and registers itself upon and against a top peripheral surface surrounding a cavity where the fan is to be located; (2) Holding the fan in place with one or more resilient mounting clips that span the distance from the top of the fan and an opposing outside bottom surface of the active heat sink; and, (3) Providing the resilient mounting clips with outward projecting mounting tabs that are flexible and resilient and that have mounting holes through which the resilient mounting clips (and the active heat sink they grip) can be attached to an assembly carrying the part to be cooled, such that the bottom of the active heat sink is in good thermal contact with that part.

Disclosed herein is a cooling device primarily for cooling integrated circuits or other electronic devices during operation. The cooling device may include a heat sink portion and a fan, or other air movement device. The outer periphery of the heat sink portion may be formed with outwardly extending lobes, leaving recessed areas between the lobes. The lobes may be sized and located so as to correspond to heat concentration areas on an electronic device package. In this manner, heat sink material may be concentrated adjacent heat concentration areas where more heat removal is required. The overall mass and size of the heat sink portion may, thus, be reduced without significantly impairing the ability of the cooling device to remove heat from an electronic device.
