  • Publication number: 20210343236
    Abstract: A zero bezel display formed from an organic light emitting diode film defines a viewing perimeter within an outer perimeter and supports control lines between the viewing perimeter and outer perimeter. A relief cut from each corner of the display film allows each side of the display film to fold to the rear of the display so that the viewing perimeter defines the viewable edge of the display.

  • Publication number: 20210318174
    Abstract: A portable information handling system has dynamic foot disposed at a bottom surface of a housing that extends and retracts to adjust cooling airflow impedance at vents disposed at the bottom surface. The dynamic foot includes an actuator in an internal cavity having opposing ramp structures interfaced by a nickel titanium wire that changes phase when heated to move the ramp structures. In the example embodiment, a push-push lock engages and disengages the ramp structures at each activation of the nickel titanium wire so that an embedded controller controls foot extension and retraction by applying current to the nickel titanium wire that heats the wire based upon detection of predetermined thermal conditions in the housing.

  • Publication number: 20210318381
    Abstract: A battery charge state indicator presents an information handling system battery charge state with an illumination element at a housing side surface in response to end user proximity detected at both first and second capacitive sensor electrodes disposed at the side surface. The capacitive sensor electrodes are supported at a nonconductive material, such as a plastic palm rest covered by carbon fiber material, to provide a proximity detection path, and are grounded to an outer surface of the information handling system housing to reduce false detection induced by end user grasp of the information handling system housing.

  • Publication number: 20210240239
    Abstract: A system and method for cooling components and a chassis in a portable information handling system includes a pressure barrier that divides the chassis into a plurality of zones, an evacuative fan in a first zone to generate airflow across components to cool the components and a hyperbaric fan in a second zone to increase air pressure in the second zone. The pressure barrier may provide thermal isolation, acoustic dampening and electromagnetic insulation. A controller communicatively coupled to the fans can operate each fan independently to cool components for improved performance and maintain a surface temperature of the chassis below a temperature for user comfort.

  • Publication number: 20210109198
    Abstract: A portable information handling system integrates an infrared time of flight sensor to detect end user presence and absence. The portable information handling system has a portable housing with rotationally coupled housing portions so that the infrared time of flight sensor orientation relative to an end user changes its alignment axis based upon an expected end user position relative to the end user. An actuator interfaces with the infrared time of flight sensor to adjust its field of view based upon sensed housing position or configuration and adjusts end user presence/absence detection at actuation to change the orientation of the time of flight sensor, such as by resetting the sensor are re-aligning the scan field of view.

  • Publication number: 20210109486
    Abstract: An information handling system manages operation of an infrared time of flight sensor to provide accurate and timely user presence and absence detection through monitoring of the time of flight distance detection for indications of object velocity that validates or invalidates a transition between the user presence and user absence states. An integrated sensor hub in a central processing unit stores distances received from the infrared time of flight sensor in a distance table in association with a time stamp of the distance measurement. During monitoring of distances received from the infrared time of flight sensor, if the integrated sensor hub detects a user absence or presence, validation of the transition is performed by analyzing the stored distances to determine a vector of velocity at the state transition.

  • Patent number: 10819920
    Abstract: An information handling system transitions security settings and/or visual image presentations based upon a user absence or user presence state detected by an infrared time of flight sensor. An operating system service monitors the state detected by the infrared time of flight sensor and other context at the information handling system to selectively apply the user absence or user presence state at the information handling system.

  • Patent number: 10635140
    Abstract: A portable information handling system rotationally couples first and second housing portions with a dual axle sequential hinge. Over a predetermined rotational orientation of one axle, a cam integrated with the axle engages a fulcrum biased into the hinge so that the fulcrum extends out of the hinge to support the information handling system at a support surface. For instance, before rotation of a lid housing portion relative to a main housing portion brings the lid housing portion into contact with the support surface, the fulcrum extends towards the support surface to raise the main housing portion and lid housing portion away from the support surface.

  • Patent number: 10606323
    Abstract: A portable information handling system processes information with processing components disposed in a main housing portion and presents the information at a display disposed in a lid housing portion. A keyboard and touchpad disposed at the upper surface of the main housing portion accept end user inputs. The touchpad translates touch inputs at a touch detection surface into cursor movement at the display and accepts presses at a touch button as input clicks. One or more antenna integrated in the touchpad to support communication of wireless signals by a transceiver disposed in the main housing, such as to support wireless local area network communications. A ground plane of the touchpad forms openings under the one or more antenna to provide a pathway for the wireless signals.

  • Patent number: 8281952
    Abstract: A container incorporating an integral roller surface for use with a roller-type liquid applicator. The roller surface may be movable from a first, operational position to a second, access position. The floor of the container may be sloped so that a well forms at a particular location, e.g., at or near one end of the container. The roller surface preferably provides access to the well during use. When the roller surface is moved to the second, access position, the sloped floor of the container may provide a second roller surface.
