Semiconductor device and method for manufacturing the same

A single crystal semiconductor substrate including an embrittlement layer is attached to a base substrate with an insulating layer interposed therebetween, and the single crystal semiconductor layer is separated at the embrittlement layer by heat treatment; accordingly, a single crystal semiconductor layer is fixed over the base substrate. The single crystal semiconductor layer is irradiated with a laser beam so that the single crystal semiconductor layer is partially melted and then is re-single crystallized, whereby crystal defects are removed. In addition, an island-shaped single crystal semiconductor layer for forming an n-channel transistor is channel-doped using a photomask and then is etched back using the photomask so that the island-shaped single crystal semiconductor layer for forming an n-channel transistor is thinner than the island-shaped single crystal semiconductor layer for forming a p-channel transistor.

Compressor unit and refrigerator using the unit

A compressor unit includes a compressor, an inverter for driving the compressor, and an over-current protective device for protecting the inverter against an output over-current. A control part controls the output voltage of the inverter when the compressor is started based on a ambient temperature detected by a temperature sensor so that the input current of the inverter does not exceed the working current value of the over-current protective device having temperature characteristics varying according to the ambient temperature. Thereby, a start torque can be increased by increasing the output voltage of the inverter without operating the over-current protective device when the compressor is stated at a low temperature when a start load is increased.

A feedback-controlled battery charger circuit (500) provides, alternatively, constant current and constant voltage to a battery (328) being charged. Current and voltage at the charger output (326) are sensed in sensing elements (308) and compared to preset reference values from reference generators for current (330) and voltage (332), thus generating error signals for both current and voltage. These error signals are amplified in separate amplifiers (530, 534); then, depending on battery voltage, one of the amplified error signals is automatically selected by a signal selector (540). The selected error signal is applied to a single compensation amplifier (554) with reactive feedback loop (552, 556); the output of the compensation amplifier with feedback (504) then controls the output current or voltage of the output stage (306). This output stage is a voltage controlled current source. The output of this voltage controlled current source is connected through an output filter (318) and sensing elements (308) to the battery (328) being charged.

Method and System for Closed-Loop Control of an Artificial Pancreas

A local extremum of a function ƒ is determined by computing a Jacobian of ƒ at a test point x by adding an imaginary part to x and a Hessian of ƒ by adding two imaginary parts to a multicomplex copy of x and extracting a third imaginary part. Solving a system of equations defined by the Jacobian and Hessian yields a delta; the process is repeated until convergence. This method is used in each of a series of time intervals to compute an insulin-delivery amount for an insulin pump. ƒ is a model-predictive-control cost function; x is a set of successive candidate insulin delivery amounts beginning from a selected time interval. A system includes a glucose monitor and a controller using glucose measurement data therefrom to determine an insulin delivery amount for a time interval by minimizing ƒ; an insulin pump provides insulin corresponding to the delivery amount.

By an image matching method, a motion detection circuit calculates a plurality of cumulative total correlation values between different divided exposure images, and searches the plurality of cumulative total correlation values for the smallest cumulative total correlation value, thereby calculating a motion vector between the different divided exposure images.

Method for radio bearer optimization through an adaptive access probability factor

A communication system (100) determines whether to establish a point-to-point or point-to-multipoint communication for conveyance of Multimedia Broadcast Multicast Services (MBMS) data based on a number of user equipments (102-104) being serviced by the communication system for MBMS service. The system broadcasts an access probability factor (154) in a control message to the user equipments. For a large number of MBMS users being counted (158), the method will select a point-to-multipoint broadcast (160). If the number of user equipments being counted is relatively small, the access probability factor is modified by a ratio of the number of point-to-point connections over the point-to-multipoint connections over the number of users being counted (174). The UE may need to join multiple base stations' in the counting procedure to obtain the system diversity gain.

Evaluating commonality of documents using segment vector, co-occurrence matrix, and common co-occurrence matrix

In evaluating commonality of documents, each sentence is represented by a binary vector whose components indicate the presence or absence of corresponding terms, whereupon the concept of a common vector among documents is introduced. One sentence vector is derived from each of the documents to form a group of sentence groups, and only components which assume “1” (one) in all the vectors are “1”, the other components being “0” (zero). The commonality of a document set is evaluated by employing the sum or squared sum of the numbers of components whose values are not zero in the individual common vectors, for all the common vectors.

Semiconductor device and display device utilizing the same

A source-drain voltage of one of two transistors connected in series becomes quite small in a set operation (write signal), thus the set operation is performed to the other transistor. In an output operation, two transistors operate as a multi-gate transistor, therefore, a current value can be small in the output operation. In other words, a current can be large in the set operation. Therefore, the set operation can be performed rapidly without being easily influenced by an intersection capacitance and a wiring resistance which are parasitic on a wiring and the like. Further, an influence of variations between adjacent ones can be small as one same transistor is used in the set operation and the output operation.
