A scheme to reduce the problem of radio interference between wireless devices such as MTC devices in a multi-RAT scenario. Wireless devices are configured (S10) for interference reporting in accordance with their capabilities. Information is collected, not only on interference measurements reported by the wireless devices, but also on device signatures (S12) and transmission patterns (S14) for the purpose of attributing interference, suffered by a reporting device, to one or more offending devices (S16). One or more mitigation techniques is then applied to the offending device and / or the reporting device (S20-S24). The scheme provides an additional stability mechanism for existing interference mitigation and co-existence schemes by using device management and avoiding potential conflicts across diverse systems. Under the assumption that geographically co-located devices are all using a common service platform, the centralised algorithm permits more efficient solutions than existing interference mitigation solutions.

Selection of certain views of a multidimensional database to materialize may be accomplished using an efficient and effective solution. A set of all potential views may be stored in a structure. A path in the structure may then be traversed in an indicated direction through the structure, the path including two or more potential views and beginning at an indicated view. Then two or more immaterialized views in the path may be compared to each other to determine which immaterialized view is the optimum choice for maximizing benefit if selected to be materialized. Then the traversing and comparing may be continually iterated through, each iteration utilizing an indicated direction different than the last, each iteration also utilizing an indicated view set at the optimum choice determined by the last iteration, the iterating continuing until it converges on a single view. That single view may then be selected for materialization.

The present invention proposes effective solutions for the design of Virtual Memory Management for applications with dynamic data types in an embedded (HW or SW) processor context. A structured search space for VMM mechanisms with orthogonal decision trees is presented.

The invention provides a method and apparatus for the reproduction of color images by multi-color dithering. Multi-color dithering is an extension of bi-level dithering for halftoning an input image using as primary colors an arbitrary number of inks. The inks may comprise standard inks or non-standard inks such as non-process color inks, opaque inks, metallic inks, variable color inks and fluorescent inks. Multi-color dithering provides a solution for creating artistic multi-color dithered images, whose screen elements are made of artistic color screen shapes such as micro-letters, symbols and ornaments. When printed at high resolution and at high registration accuracy, multi-color dithering using large dither arrays incorporating artistic dither shapes provides an effective solution for preventing counterfeiting. The use of non-standard inks offers additional protection. Multi-color dithering also offers a solution for printers requiring that all inks are printed side by side, without overlaps.

Embodiments of the present invention provide devices and methods that allow a continuous connection to be maintained between a medical device that is capable of communicating over a cellular network and a sensor network. Medical devices that are capable of communicating over a cellular network represent one form of assistive technologies for the home that can allow senior citizens to remain at home for longer, improve the quality of life, and provide more cost-effective solutions than residential care. Removing a SIM card (subscriber identity module, a removable smart card for cell phones that securely stores the service-subscriber key used to identify a mobile phone) from a cellular communication device requires the device to be powered down. However, powering down a medical device can result in a loss of important data.

Method and system for a wet / wet differential pressure sensor based on microelectronic packaging process. A top cap with a hole can be attached to a topside of a MEMS-configured pressure sense die with a pressure sensing diaphragm in order to allow sensed media to come in contact with the topside of the pressure sensing diaphragm. An optional constraint with a hole for stress relief can be attached to a backside of the pressure sense die. Adhesive and / or elastomeric seals and / or solder can be utilized to seal the pressure sense die allowing sensed media to come in contact with both sides of the pressure sensing diaphragm without coming into contact with wirebonds and other metallized surfaces. The MEMS-configured pressure sense die can also be bonded to a substrate with standard die attach materials. Such microelectronic packaging processes yield a high performance and cost effective solution thereby providing wet-wet pressure sensing capability.

The present patent application discloses a USB token that advantageously mimics a human interface device such as a keyboard in interacting with a host computer, thus removing the need for pre-installation of a dedicated device driver. This is accomplished by requiring the host computer to direct the input of the attached human interface devices of the keyboard type, including the USB token, exclusively to the program interacting with the USB token, by using cryptographic algorithms based on a shared secret, which require less data to be transferred than PKI-based algorithms, and by employing an efficient encoding scheme that minimizes the time needed to exchange information with the USB token, and minimizes the probability of generating ambiguity with input that might legitimately be generated by other attached human interface devices. By using only symmetric encryption and the low-speed USB protocol, a single low-performance processor may be used, which results in a more cost-effective solution than PKI USB tokens emulating the combination of smart cards and smart card readers or USB tokens presenting themselves to the host computer as mass storage devices. The overall security is increased by adding a second authentication factor consisting of a static password entered by the user, and by limiting the number of valid token response that can be generated or retrieved in a usage session.

We propose a class of mechanisms to support a new style of synchronization that offers simple and efficient solutions to several existing problems for which existing solutions are complicated, expensive, and / or otherwise inadequate. In general, the proposed mechanisms allow a program to read from a first memory location (called the “flagged” location), and to then continue execution, storing values to zero or more other memory locations such that these stores take effect (i.e., become visible in the memory system) only while the flagged memory location does not change. In some embodiments, the mechanisms further allow the program to determine when the first memory location has changed. We call the proposed mechanisms conditional multi-store synchronization mechanisms.

Different from conventional equalizers, the output of an SAIC (Single Antenna Interference Cancellation) linear equalizer in GSM / EDGE wireless communication systems is a real signal combined from two real FIR (Finite Impulse Response) filter outputs. Each of the FIRs separately uses the real and imaginary components of the ½π de-rotated received signal as input. The real-valued output of the SAIC equalizer creates difficulty to estimate and correct the frequency errors due to receiver LO and Doppler shift. Disclosed is an efficient and effective solution to the estimation and correction of the frequency error through an assistant signal generated by two additional FIR filters. The assistant signal and the SAIC equalizer output are used to estimate the frequency error, which is combined with the SAIC equalizer output and the assistant signal to give the frequency error corrected SAIC equalizer output.
