A terminal 211 measures pilot signals transmitted in directional (beam) patterns from an adjacent cell and an own cell, and estimates reception qualities with the presence (high) / absence (low) of the interference from the adjacent cell. The terminal 211 requests data rate request values (DRC1, DRC2) corresponding to the reception qualities with the presence / absence of the interference to the base station 201. The base station 201 shares beam direction schedule with an adjacent cell base station, and confirms the presence / absence of interference to the terminal 211 for each slot. In accordance with the presence / absence of the interference, the base station 201 selects a suitable one of the two values of the data rates requested from the terminal 211, and modulates the data and transmits it.

An integrated circuit package includes a balanced-part structure. The condition of thermal stress of chips connected on a substrate decides the amount, locations, weights, and the material of at least a balanced-part fastened on a substrate. The balanced-part is fastened on the substrate to balance stress distribution before an adhering heat sinks process and a packaging molding compound process. The balanced-part also decreases thermal stress affection and avoid warpage defects of the integrated circuit packages.

The object of the invention is to provide a slotted current acquisition coil according to the Rogowski principle in which the printed circuit board base of the measuring coil can be opened to insert an electrical conductor to be measured without having to interrupt the latter. To this end, the two printed circuit board segments linked together by a hinge are opened. Twisting a single-piece printed circuit board also opens the arrangement for inserting the conductor to be measured.

An interferometric fiber optic encoder readhead for sensing the displacement of a scale grating is disclosed. The detector channels of the readhead are fiber optic detector channels having respective phase grating masks. The fiber optic encoder readhead is configured to detect the displacement of interference fringes arising from the scale grating. In various exemplary embodiments, the fiber optic readhead is constructed and operably positioned according to various design relationships that insure a compact mounting and a relatively ideal sinusoidal signal as a function of displacement. Accordingly, high levels of displacement signal interpolation may be achieved, allowing sub-micrometer displacement measurements. The fiber optic encoder readhead may be assembled in a particularly accurate and economical manner and may be provided in a package with dimensions on the order of 1–2 millimeters.

A device for measuring fluid flow rates over a wide range of flow rates (<1 nL / min to >10 μL / min) and at pressures at least as great as 2,000 psi. The invention is particularly adapted for use in microfluidic systems. The device operates by producing compositional variations in the fluid, or pulses, that are subsequently detected downstream from the point of creation to derive a flow rate. Each pulse, comprising a small fluid volume, whose composition is different from the mean composition of the fluid, can be created by electrochemical means, such as by electrolysis of a solvent, electrolysis of a dissolved species, or electrodialysis of a dissolved ionic species. Measurements of the conductivity of the fluid can be used to detect the arrival time of the pulses, from which the fluid flow rate can be determined. A pair of spaced apart electrodes can be used to produce the electrochemical pulse. In those instances where it is desired to measure a wide range of fluid flow rates a three electrode configuration in which the electrodes are spaced at unequal distances has been found to be desirable.
