A silicon-on-insulator (SOI) Read Only Memory (ROM), and a method of making the SOI ROM. ROM cells are located at the intersections of stripes in the surface SOI layer with orthogonally oriented wires on a conductor layer. Contacts from the wires connect to ROM cell diodes in the upper surface of the stripes. ROM cell personalization is the presence or absence of a diode and/or contact.

Embodiments of the invention are concerned with improvements to antenna systems, in particular beamforming antenna systems. Embodiments provide an improved beamformer arrangement for receiving and transmitting of signals by antenna elements. Embodiments are particularly well suited to use for transceiving of radio signals by base stations, such as are commonly found in cellular networks. In one aspect, embodiments provide a beamformer for use in processing signals received, or transmitted, by a first antenna element, the beamformer comprising a first set of ports and a second set of ports, wherein the first set of ports is connected to at least two antenna elements including said first antenna element and the second set of ports is connected to a connecting port, wherein the beamformer is arranged to generate at least first and second output beams from signals received from the at least two antenna elements and to transform signals received via the second set of ports into signals for transmission by the at least two antenna elements, wherein the beamformer is arranged to combine said generated at least first and second output beams at the connecting port such that said signals from said first antenna element are constructively combined at the connecting port, and to combine said at least first and second output beams at the connecting port such that signals from antenna elements other than the first antenna element are destructively combined at the connecting port, wherein the connecting port is arranged so as to provide access to individual said signals received, or transmitted, by said at least two antenna elements. In particularly preferred arrangements the first set of ports is connected to three or four antenna elements.

A head coil arrangement for a magnetic resonance device has a housing on or in which a number of coils are arranged, the housing having at least two housing parts that can be moved toward each other for adjustment to different head sizes.

A magnetic resonance imaging (MRI) method for the quantification of the longitudinal (T₁) and/or transverse (T₂) relaxation times in a sample is provided. According to this MRI method a sample is subjected to an unbalanced steady state free precession (SSFP) sequence comprising a series of consecutive radiofrequency (RF) pulses. By means of this unbalanced SSFP sequence, the first order SSFP FID signal (F₁), the lowest order SSFP FID signal (F₀), and the lowest order SSFP Echo signal (F₋₁) are acquired. Based on the F₀-signal, the F₁-signal and the F₋₁-signal the longitudinal (T₁) and/or transverse (T₂) relaxation times of the sample are determined.

A MEMS device package and a method of manufacturing the same. The MEMS device package includes a device substrate having a surface on which a MEMS active device is formed, and multiple sealing pads arranged around the MEMS active device so that the sealing pads provide electric paths for the MEMS active device. In addition, the MEMS device package may include a cap substrate bonded to the device substrate through the multiple sealing pads, the cap substrate including a trench, within which the MEMS active device is positioned, and via holes. One or more outer electrode pads may be formed on one surface of the cap substrate to be electrically connected with the multiple sealing pads through the via holes. Because there are several bonding and sealing areas between the device substrate and the cap substrate, the sealing intensity is strengthened.

A display device includes a cholesteric liquid crystal writing tablet and a piezoelectric transducer. The piezoelectric transducer is subjected to a mechanical force that generates a voltage that is applied to the writing tablet that erases writing on the writing tablet. A further feature is a display device comprising a cholesteric liquid crystal display and a piezoelectric transducer. The piezoelectric transducer is subjected to a mechanical force that generates a voltage that is applied to the display that places the display in at least one of a color reflective planar state, a substantially transparent focal conic state and a gray scale state. Also featured is a method of erasing a cholesteric liquid crystal writing tablet.

The invention discloses an optical signal detection device for physiological detection and a method for analyzing sample components. Exciting light goes to a sample in one direction selectively for production of transmission raman signals in a transmission modle or goes to the sample in another direction for production of reflection raman signals in a reflection mode. Through the analysis of transmission and reflection raman signals, content of components in the sample can be determined.

Methods and systems for reducing illumination intensity while scanning over large particles are presented herein. A surface inspection system determines the presence of a large particle in the inspection path of a primary measurement spot using a separate leading measurement spot. The inspection system reduces the incident illumination power while the large particle is within the primary measurement spot. The primary measurement spot and the leading measurement spot are separately imaged by a common imaging collection objective onto one or more detectors. The imaging based collection design spatially separates the image of the leading measurement spot from the image of the primary measurement spot at one or more wafer image planes. Light detected from the leading measurement spot is analyzed to determine a reduced power time interval when the optical power of the primary illumination beam and the leading illumination beam are reduced.

Systems and methods to minimize signal loss and distortions with connections of audio sources and speakers are disclosed. Fiber optic cables are used instead of conventional cables. The audio signals are kept always in the analog domain, no matter if they are in optical or electric format. The strength of the audio signals can be controlled by a volume control unit. A small amplifier unit can either directly plugged to speakers are connected to the speakers via a short speaker cable. A preamplifier is no more necessary in the system.
