  • Publication number: 20190317576
    Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU to a location distal the CPU with a vapor chamber thermally interfaced with the CPU. A pressure adapter interfaced with the vapor chamber selectively changes the pressure within the vapor chamber to adjust the saturation point of a liquid in the vapor chamber that manages thermal transfer efficiency. For example, a controller interfaced with the pressure adapter modifies thermal transfer characteristics of the vapor chamber to control thermal conditions at the information handling system, such as in response to a temperature sensed at a housing surface, a battery, a display or at other locations of the information handling system.

  • Publication number: 20190317571
    Abstract: A portable information handling system transfers thermal energy associated with operation of processing components between rotationally coupled housing portions through a thermal spreader disposed between the housing portions, such as a sheet having one or more layers of graphite. A tensioning assembly engages the thermal sheet to manage excess material associated with varying rotational orientations of the housing portions.

  • Publication number: 20190317572
    Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion through a graphite torsion spring formed from a graphite sheet by cutting arms to extend out of opposing corners of a central portion and rolling the central portion about a central axis. The graphite torsion spring passes thermal energy between the housing portions with the spring releasing tension as the housing portions rotate from a closed to an open position and the central axis disposed about a hinge pin that couples the housing portions to each other.

  • Publication number: 20190317574
    Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU from a main housing portion to a lid housing portion with thermal conduction through a hinge assembly that rotationally couples the main and lid housing portions to each other. For example, thermal conduits insert into a hinge body and transfer thermal energy across the hinge body through a thermally conductive interface, such as the hinge body itself, thermal grease disposed in the hinge body, a liquid that fills a cavity of the hinge body shared by the thermal conduits, and a vapor chamber integrated in the hinge body.

  • Publication number: 20190317575
    Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion to a vapor chamber integrated in a lid housing portion that distributes the thermal energy across the lid housing portion. A hinge protrusion formed in the lid housing portion defines a cylindrical opening that accepts a hinge pin to rotationally couple the housing portions to each other. The cylindrical wall defines a barrier with the vapor chamber so that a thermal conduit passing from the main housing portion to the hinge pin transfers thermal energy from the hinge pin through the cylindrical wall to the vapor chamber.

  • Publication number: 20190317578
    Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a first housing portion to a thermal exchanger in a second housing portion through a hinge that rotationally couples the first and second housing portions. The hinge has first and second axles that each define a channel. Fluid heated at the first housing portion passes through the channel to the thermal exchanger where thermal energy is rejected from the system. In one embodiment, a second hinge having first and second axles that each define a channel provides a return path for the fluid from the second housing portion to the first housing portion.

  • Patent number: 10429904
    Abstract: An information handling system having rotationally coupled housing portions supports a flexible display disposed across the housing portions with a hinge structure that manages flexible display curve radius in a folded configuration. A dual axis synchronized hinge defines the flexible display bend radius by the distance between the hinge axes and by a shape memory alloy planar support fixed in position relative to the hinge. A ramp structure engages a flexible display frame during rotation to an open position to maintain the display frame in a planar configuration.

  • Patent number: 10332702
    Abstract: In some examples, a housing may include a keyboard having a plurality of keys. An individual key of the plurality of keys may include a keycap, an organic light emitting diode (OLED) film (or sheet), a key mechanism, and a base. When power is provided to contacts on the base of the individual key, the power may travel across conductive traces (or wires) in the key mechanism to pads on the OLED film, causing the OLED film to emit light. The light from the OLED film may illuminate a character or symbol embedded into the keycap or the OLED film may be shaped into the character or the symbol and embedded into the keycap. The housing may be (i) separate from and communicatively coupled to a second housing that includes one or more processors or (ii) physically attached to a display device as part of a laptop device.

  • Patent number: 6687791
    Abstract: Various embodiments of a method and system for sharing a cache such as an on-chip L1 cache are disclosed. In one embodiment, a processing device includes a shared cache and a plurality of processors that are each coupled to the shared cache and each configured to store the result of a data integrity operation in the shared cache. Each of the processors performs the same data integrity operation on the same data to generate its result. Because the results are stored in the shared cache, a first processor may quickly access and operate on the results. In one embodiment, the first processor may perform a comparison operation or voting operation on the results stored in the shared cache.

  • Patent number: 5187540
    Abstract: An optical system, for the remote determination of the position and orientation of a body in a frame of reference, e.g. a helmet within a cockpit of an aircraft, comprises co-operating light emitting means and light sensing means. At least three of one type of said co-operating means are located on the body and scanning optic means are arranged to scan the frame of reference with a pair of planar beams. The planes of the beams are inclined to each other and are arranged to provide a light path between the co-operating means. A signal processing means is operative to provide a signal indicative of the position and orientation of a body and a time during the scan of each respective beam in which the beam is coincident with each of the said means mounted on the body. In one embodiment three light sensing means are located on the body and the planar beams are beams of light from a light emitting means.

  • Patent number: 4651138
    Abstract: An intruder alarm system includes a number of sensors each of which comprises first and second series-connected resistances and a sensor switch connected in parallel with the first resistance. The first resistances of each sensor are different in value from one another, but their values are related in a known manner. The sensors are connected in series with one another by a connecting cable and to a constant current source. The voltage developed across the series-connected sensors is applied to a circuit arrangement operable to offset the effect of the total resistance of the second resistances of each sensor and of the connecting cable. An analogue-to-digital converter is responsive to the output of the circuit arrangement to deliver a digital output to an indicator which indicates the actuation of any sensor.
