Embedded commericals within a television receiver using an integrated electronic billboard

Abstract: A television receiver is equipped with a graphics generator which is capable of generating a single or multiple graphic images from data representing commercial advertisements stored in a memory device. The elements of this arrangement include a micro-controller, a memory device, a graphics and memory controller, a pallet controller and a video switch. The images corresponding to the commercial advertisements are displayed to the consumer when a control function of the television receiver is activated. Alternatively, the images may be displayed in response to an internal clock. The images presented may be static or animated and may occupy a small portion of the screen or the full screen.

Amide proton transfer imaging of adult diffuse gliomas: correlation with histopathological grades.

Abstract: Background.Amideprotontransfer(APT)imagingisanovelmolecularMRItechniquetodetectendogenousmobileproteinsandpeptides through chemical exchange saturation transfer. We prospectively assessed the usefulness of APT imaging in predicting the histological grade of adult diffuse gliomas. Methods. Thirty-six consecutive patients with histopathologically proven diffuse glioma (48.1+14.7 y old, 16 males and 20 females) were included in the study. APT MRI was conducted on a 3T clinical scanner and was obtained with 2 s saturation at 25 saturation frequency offsets v ¼ 2 6t o+6 ppm (step 0.5 ppm). dB0 maps were acquired separately for a point-by-point dB0 correction. APT signal intensity (SI) was defined as magnetization transfer asymmetry at 3.5 ppm: magnetization transfer ratio (MTR)asym ¼ (S[23.5 ppm] 2 S[+3.5 ppm])/S0. Regions of interest were carefully placed by 2 neuroradiologists in solid parts within brain tumors. The APT SI was compared with World Health Organization grade, Ki-67 labeling index (LI), and cell density.

Video retrieval of MPEG compressed sequences using DC and motion signatures

Abstract: Signatures from MPEG or Motion JPEG encoded video clips are extracted based on the luminance, chrominance, and motion vector values. The signatures are stored in a database, along with corresponding location, size, and time length information. The signature of a query video clip, also encoded in the MPEG or Motion JPEG format, is extracted. The signature of the query video clip is comparred with the signatures stored in the meta database, with video clips having signatures similar to the signature of the query video clip identified. The video clips are then retrieved and displayed by selection of a user.

Limitation of inductive power transfer for consumer applications

Abstract: Inductive power transmission is proposed more and more also for consumer applications. In this work, limitations with respect to efficiency of the whole magnetic system are investigated. The power efficiency of a given structure is dependent on resonant matching and on the load impedance. First, the matching conditions for optimal power efficiency are derived. Then the achievable efficiency for inductive transmission structures with varying distance and size ratios are investigated. Recent publications on inductive power transmission are evaluated and discussed based on these results. As a conclusion, inductive power transmission in a larger space (e.g. a whole room) is very inefficient. On the other hand, inductive power transmission at a surface can be efficient as conventional power supplies. Based on this insight, an inductive power transmission pad has been designed and built, with the purpose to charge mobile devices like mobile phones. It can charge an arbitrary number of devices and allows free positioning of the devices on the pad. It consists of an array of planar transmitter coils and has a size of 20 cm x 26 cm. It can detect the position of a receiver and activates only the coils underneath a receiver.

Choosing governance modes for external technology sourcing

Abstract: This study examines the effect of uncertainty on governance mode choice of interfirm relationships in new business development (NBD). We combine transaction cost economics and real options reasoning, arguing that in the early stages of NBD, where technological and market uncertainty are very high, companies are better off using governance modes that are reversible and involve a low level of commitment. When uncertainty has decreased as a result of prior R&D investments, transaction costs considerations become dominant and companies will shift towards governance modes that are less reversible and more hierarchical. We argue that technological distance leads to less hierarchical governance modes and prior cooperation between firms leads to subsequent choices for more hierarchical modes. Finally, we propose that higher exogenous uncertainty leads to less hierarchical governance modes.
