  • Publication number: 20140028502
    Abstract: A method for constructing a wireless communications apparatus includes attaching a three dimensional antenna having a first end and a second end to a printed circuit board (PCB) using a spring-loaded attachment mechanism. The three dimensional antenna is attached in an orientation that is perpendicular to a mounting surface of the PCB. The first end of the three dimensional antenna is further soldered to the PCB.

  • Patent number: 8633893
    Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

  • Patent number: 8625024
    Abstract: A webcam with an optical lens that can manually be moved into a position in front of the camera lens. The lens may slide or be rotated to a position in front of the camera lens. The optical lens may be a zoom lens, such that, in combination with the lens of the camera, a fixed zoom or magnification function is provided. Alternately, at least a second lens may also be provided, such as to provide two fixed zoom positions. The two lenses could be moved together with a single mechanical structure, or separately with two different manual controls.

  • Patent number: 8606950
    Abstract: A multimedia data processing system and method which transparently processes video and/or audio streams in real-time. The operation of a system in accordance with an embodiment of the present invention does not require any intervention from, or involvement of, either the producer of the video and/or audio stream, or the client application. With such a transparent solution, video and/or audio streams can be processed seamlessly, and completely independently of the specific client application that the user chooses to use. In one embodiment, the invention uses an external service to monitor new processes and add code to these processes. The invention inserts into the system by hot-patching the software in memory and by only looking at select service calls.

  • Publication number: 20130321273
    Abstract: A control devices includes a key having a top surface configured to be pressed by a user, and a resistance device coupled to the key and configured to provide a resistance force to the key that opposes a user force applied to the top surface. A force sensor is coupled to the resistance device and is configured to detect the user force applied to top surface. A control circuit is coupled to the resistance device and is configured to change the resistance force of the resistance device according to a force profile.

  • Patent number: 8565448
    Abstract: A dynamic bass equalization circuit has an amplitude dependent gain that is dependent upon the audio electrical signal amplitude and a dynamically adjusted frequency response that varies with the amplitude dependent gain. In one implementation, the dynamic bass equalization circuit includes a Sallen-Key high pass filter that includes an amplifier with a negative feedback path. The dynamically adjusted frequency response is provided by a parallel pair of reversed diodes connected in the negative feedback path.

  • Patent number: 8545323
    Abstract: A compact game controller incorporates an efficient and compact force feedback mechanism. Forces are generated at one of the controls of the controller in reaction to an action in a video game. The type of controller that can be held with two hands is limited in terms of size and internal space and in wireless versions is limited in terms of battery power. Efficient power consumption in the controller enables considerable usage time between battery replacement or recharging in wireless versions. The force feedback mechanism incorporates a double reduction gear system with a unique geometry which enables usage of a compact and energy efficient motor. The efficient force feedback mechanism and assembly can therefore be packaged within a compact ergonomic controller.
