Abstract:
Embodiments of a backlit keyboard assembly are described. A keycap (202) assembly is mounted into a case web (104) having intersecting ribs. A flange (210), which can be angled, is on the bottom perimeter of the keycap (202) and a correspondingly shaped flange (212) is on each rib of the case web (104). An overlap of the keycap flange (210) and the case web flanges (212) prevents direct sighting of the backlight light source (208) and also provides a more evenly distributed halo around the keycap (202), thereby improving both aesthetics and functionality by providing better light control and contrast.
Abstract:
A force sensor and force-sensing structure (200a, 200b, 200c, 200d) for use as input to an electronic device (100). A user touch event may be sensed on a display (104), enclosure, or other surface associated with an electronic device using a force sensor adapted to determine the magnitude of force of the touch event. The sensor output, corresponding to the magnitude of force, may be used as an input signal, input data, or other input information to the electronic device. A force sensor may include an array of upper electrodes (211) disposed on a first substrate (210) and a compliant medium (230) disposed in a gap between the first substrate and a second substrate (220). At least one lower electrode (221) may be disposed on the second substrate. The first substrate may be configured to deflect relative to the second substrate over a localized region when a force is applied to the force-receiving surface.
Abstract:
The present application describes various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes internal components configured to fit within a relatively thin outer enclosure.
Abstract:
An input device is disclosed. The input device includes a movable touch-sensitive track pad capable of detecting an object in close proximity thereto so as to generate a tracking control signal. The input device also includes a movement indicator capable of detecting the movements of the movable track pad so as to generate one or more other control signals (e.g., button signals). The control signals can be used to perform actions in an electronic device operatively coupled to the input device.
Abstract:
A desktop computing system having at least a central core surrounded by housing having a shape that defines a volume in which the central core resides is described. The housing includes a first opening and a second opening axially displaced from the first opening. The first opening having a size and shape in accordance with an amount of airflow used as a heat transfer medium for cooling internal components, the second opening defined by a lip that engages a portion of the airflow in such a way that at least some of the heat transferred to the air flow from the internal components is passed to the housing.
Abstract:
The three dimensional surface shape of one or more layers of a reflective object is determined by examining one or more captured images reflected from the reflective object. Curved surfaces reflect a distorted image altered by the surface shape. By analyzing one or more captured images of the distorted reflected images, the shape of the surface that caused the distortion is estimated. A captured distorted image is compared to a reference undistorted image having known geometric properties. A system to capture and process such images is assembled from components including an image capture assembly such as a digital camera to capture reflected images and a positioning assembly on which to orient the components with respect to each other. Multiple surface layers of the reflective object are separately estimated using polarizations, luminance levels, chroma values or combinations thereof contained in one or more captured images.
Abstract:
An orbiting relay assembly may be provided that has one or more switches. The switches may be provided with electrical contacts. An actuator such as an electromagnetic actuator may rotate guiding structures such as a rotating yoke about a rotational axis. The guiding structures may have portions that receive movable electrical coupling structures such as metal balls or cylinders. There may be multiple movable electrical coupling structures in a relay. The electrical coupling structures may be distributed radially outwards from the rotational axis, may be distributed circumferentially about the rotational axis, or may be distributed axially parallel to the rotational axis. The guiding structures may be configured to place the switches in one or more different operating states by moving the metal balls or other movable electrical coupling structures about the rotational axis.
Abstract:
A dynamic input surface for an electronic device and a method of reconfiguring the same is disclosed. The input surface has a partially-flexible metal contact portion defining an input area, and a group of indicators. The indicators may be group of holes extending through the contact portion. The group of holes may be selectively illuminated based on a gesture performed on the contact portion. A size of the input area may be dynamically varied based on the gesture. Additionally, the group of indicators indicates a boundary of the input area.
Abstract:
This application relates to determining uniformity of a housing for a computing device based on characteristics of a reflected pattern of light incident upon the housing. The reflected pattern of light can include an array of shapes such as dots whose orientation and location can provide indications of uniformity for the housing. The array of shapes are analyzed to determine certain geometric properties such as area for each shape in the array of shapes. The geometric properties can thereafter be compared to a predetermined geometric, threshold, or tolerance value, and each shape can be assigned a rank of uniformity. Once a rank of uniformity is defined for each shape, a compilation of uniformity values can be generated and used to find portions on the housing where the housing is not uniform or flat.
Abstract:
Apparatuses and methods for an electronic device to control the application of friction to a rotary input control with a shaft. In one example, the apparatus may include a spring bar member having a first surface and a second surface, the first surface positioned adjacent to the shaft; and a movable tension member positioned to engage the second surface of the spring bar; wherein as the tension member engages the spring bar, the spring bar engages the shaft and applies a frictional force to the shaft. In this manner, the apparatus can controllably apply a friction force of a desired amount to the rotary input control.
