Abstract: In some embodiments, an apparatus includes a housing and an image sensor that is coupled to the housing and has a field of view. The apparatus also includes a non-imaging optical system coupled to the housing and disposed outside of the field of view of the image sensor. The non-imaging optical system can output diffuse light in a set of directions to a surface to produce scattered light. The image sensor and the non-imaging optical system are collectively configured such that during operation, the image sensor receives at least a portion of the scattered light.

Abstract: In some embodiments, an apparatus includes a housing and an image sensor that is coupled to the housing. The apparatus also includes a non-imaging optical system coupled to the housing that can output light to a surface and produce a scattered light component and a specular reflected light component. The image sensor and the non-imaging optical system are collectively configured in such a manner that during operation, the image sensor receives from a surface (1) at least a portion of the scattered light component and not the specular reflected light component or (2) at least a portion of the scattered light component having a magnitude and at least a portion of the specular reflective light component having a magnitude less than the magnitude of the portion of the scattered light component.

Abstract: In some embodiments, a stylus device includes two switch mechanisms, one disposed at the stylus tip portion and the other disposed at the stylus end portion. The stylus device also includes a wireless transceiver that allows the stylus device to communicate back to an electronic host device (e.g., an electronic tablet) in response to a user contacting the surface of a host device with the stylus tip portion or the stylus end portion. This enables, for example, a wide range of dual stylus device functions for electronic tablet applications. For example, the stylus device can be used to write and/or draw with the stylus tip portion and then can be flipped to the stylus end portion to erase as a user would generally do with a conventional pencil on paper. In another example, the stylus device can include a marker color tip on the stylus tip portion and a color blender on the stylus end portion.

Abstract: A stylus has a body portion and a tip portion coupled to an end of the body portion. The body portion defines a first cross-sectional area and is configured to be engaged by a user. The tip portion has a first end disposed adjacent to the body portion and having the first cross-sectional area, and a second end defining a second cross-sectional area different from the first cross-sectional area. The tip portion is formed from a flexible material that elastically deforms when placed in contact with a touch sensitive display to define an engagement surface that is input to the touch sensitive display. The engagement surface has a first size when the stylus is in a first configuration and a second size different from the first size when the stylus is in a second configuration.

Abstract: A method can include receiving a signal representing a first touch event and receiving a signal representing a first end portion of a stylus device being activated. Based on receiving the signal representing the first touch event and based on receiving the signal representing the first end portion of the stylus device being activated, a signal can be sent such that a graphical user interface (GUI) is modified according to a first functionality. A signal representing a second touch event and a signal representing a second end portion of the stylus device being activated can also be received. Based on receiving the signal representing the second touch event and based on receiving the signal representing the second end portion of the stylus device being activated, a signal can be sent such that the GUI is modified according to a second functionality.

Abstract: An arrangement for managing cables of accessories such as earphone sets, chargers, and synchronization arrangements used with portable electronic devices is provided by a flexible and elastically deformable loop that extends from a base that optionally includes a hook or other loop retention feature. The base may be alternatively configured to be integrally formed with a component of an accessory, or be configured as a discrete clip that may be detachably coupled to the component, or to the cable portion of the accessory. The elastically deformable loop is configured to be removably fastenable by a user to articles such as buttons on clothing to help keep cables out of the way when the accessory is in use. In addition, the elastically deformable loop may be used to keep an accessory cable neatly stowed during storage by being stretched around a bundled cable and then secured on the hook.

Abstract: A wireless headset having a user interface configured to allow the user to utilize the full functionality of the headset while minimizing the number of physical control inputs necessary is described. The user interface may have a user input control that is configured to control more than one function of the headset. The user interface may also provide audio as well as visual outputs to the user to indicate a particular functionality of the headset being controlled by the user or a particular status of the headset.

Abstract: Peripheral devices having one or more pedals are provided, wherein the peripheral devices are slip resistant with respect to a surface, such as a floor, upon which the peripheral devices are placed or positioned. A user of such peripheral devices can use a heel against the floor surface through the peripheral device to anchor the peripheral device and can use the heel to correct the position of the peripheral device if it slips by applying a counterforce. The peripheral device(s) include multiple springs per pedal and associated software for accommodating a non-linear force response for a more realistic user experience.

Abstract: A text input device for videogame controller may comprise a text input device housing comprising a keypad. The text input device housing forms a friction-fitting cavity for engaging the videogame controller. An electrical interface plug can be disposed inside the friction-fitting cavity, and can engage with a socket on the videogame controller when the text input device is engaged. The electrical interface plug transmits electrical signals to and from the videogame controller.
