75results about How to "Less flexibility" patented technology

Disclosed are techniques for adaptive interpolation filtering of luminance and chrominance samples in the context of motion compensation in video encoding or decoding. A two-dimensional interpolation filter of n×m coefficients may be separable, i.e., it may be separated into two one-dimensional filters with m and n coefficients, respectively. The bitstream may include, per video unit and sub-sample position, information indicating whether to use a newly-generated, a cached, or a default filter that may be a separable two-dimensional filter. The information may be structured in a way that takes advantage of the two-dimensional filter being separable. When a newly-generated filter is signalled, the bitstream may contain information pertaining to the characteristics of the newly-generated filter, such as its coefficients. A decoder may fetch this information from the bitstream to create the filters which are applied to samples of the video unit. An encoder may create a bitstream as described.

An airway implant device for maintaining and / or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The airway implant device includes a deformable element to control the opening of an air passageway and a tether. Preferably the deformable element is an electroactive polymer element. Energizing of the electroactive polymer element provides support for the walls of an air passageway, when the walls collapse, and thus, completely or partially opens the air passageway. Also disclosed is an implant for stabilizing the tongue, the implant having an anchoring portion for securing a first end of the implant with the mandibula; a control portion connected with the anchoring portion, configured for selectively activating the implant; a flexible portion connected at its proximal end with the control portion, where the flexible portion has three-dimensional flexibility in a first state and where the flexible portion has a lesser three-dimensional flexibility in a second state, and where the flexible portion is selectively switchable between the first and second state by the control portion; and an anchoring portion for connecting the implant with the base of the tongue connected with the distal end of the flexible portion. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

A magnetic mount is provided for easily mounting, positioning, and orienting a camera, sensor or other directionally sensitive electronic device. In one example the magnetic mount is a camera mount. The camera mount has a camera part that has an image sensor, electronics, battery, and communication components. The housing for the camera part has a generally concave mounting surface, with a magnet positioned inside the camera housing and adjacent to the camera mounting surface. A base part has a base mounting surface that is constructed to be attracted to the magnet. In one example, the base mounting surface is dome-shaped, with a convex curvature constructed to mate with the concave curvature of the camera mounting surface. The base part is mounted to a stable support, and the camera mounting surface brought near the base counting surface. The magnetic attractive forces pull the camera part firmly to the base part, thereby securely positioning and orienting the camera. However, the camera may be readily repositioned by pushing the camera into a new position. The size and shape of the complementary mounting surfaces may be selected according to positioning requirements.

A catheter with basket-shaped electrode assembly with spines configured for hyper-flexing in a predetermined, predictable manner when a compressive force acts on the assembly from either its distal end or its proximal end. At least one spine has at least one region of greater (or hyper) flexibility that allows the electrode assembly to deform, for example, compress, for absorbing and dampening excessive force that may otherwise cause damage or injury to tissue wall in contact with the assembly, without compromising the structure and stiffness of the remaining regions of the spine, including its distal and proximal regions. The one or more regions of greater flexibility in the spine allow the spine to flex into a generally V-shape configuration or a generally U-shape configuration.

A method is disclosed for evaluating the physical properties of a sample, for example, the grain size in a polycrystalline material. An ultrasound field is generated in a local region of the sample with a non-contact source, such as a pulsed laser, such that the generated ultrasound diffuses away from said local region. After waiting until the generated ultrasound field has reached a diffusion regime, the resulting ultrasound field is measured with a non-contact detector. Parameters are adjusted in a mathematical model describing the predicted behaviour of the ultrasound field in the diffusion regime to fit the detected ultrasound field to the mathematical model. In this way, parameters dependent on the physical properties of the sample, such as the diffusion coefficient and absorption coefficient, can be derived. The grain size, for example, can be estimated from these parameters preferably by calibrating the diffusion coefficient to grain size.

In a programmable logic device having high-speed serial interface channels, a clock distribution network for providing one or more high-speed clocks to dynamic phase alignment circuitry of those high-speed serial interfaces includes at least one bus that is segmentable (e.g. using tristatable buffers). This allows the bus to be divided into different portions that can be connected to different clock sources when the high-speed serial interfaces are running at different speeds. In one embodiment, the segmenting elements (e.g., the aforementioned buffers) are located between selected channels (e.g., every fourth channel), limiting the size of the different segments. In another embodiment, segmenting elements are located between each channel, allowing complete user freedom in selecting the sizes of the segments. Thus, instead of providing a bus for every clock source, multiple clocks can be made available to different channels by segmenting a single bus.
