摘要:
A method and apparatus for translating a voltage control signal to switch a drive output, having a circuit with a pair of branches, each branch having a pull down device, respective branches receiving complementary components of the voltage control signal; a pull up device, in series with a respective pull down device, and each being driven by a positive feedback signal reflecting a state of conduction of the pull up device; and a current blocking device, in series with the pull up device, having a control input for impeding a current flowing in series to a respective pull down device. One current blocking device is controlled to selectively block a current flow through one of the branches, while permitting current flow through the other branch. The state of the voltage control signal is switched, current flow through both branches is resumed. In a preferred embodiment, the complementary components of the voltage control signal are formed with an inverter. A transmission gate is provided, having a pair of complementary inputs from the nodes between the pull up devices and pull down device in series, to modulate the optical state of a liquid crystal light modulating structure. The pull down devices, pull up devices, current blocking devices, inverter and complementary device transmission gate are each preferably formed in a silicon integrated circuit, with the liquid crystal light modulating structure formed on the surface.

The invention relates to method and a system of interpreting angular orientation data. It is determined, whether the angular deviation of a current angular orientation (C) of a sensor device (12) from a last extreme angular orientation (L) currently decreases after having increased before up to a provisional new extreme angular orientation (P), thereby determining that the provisional new extreme angular orientation (P) is a new extreme angular orientation. Information relating to a new extreme angular orientation, such as an angular range of motion, may be output to a user.

A method for automatically monitoring consciousness of a person and triggering an alarm if the monitored person is not in a state of full consciousness is provided. The method comprises the steps: monitoring at least one aspect of the behavior of the person (S1); analyzing whether the monitored behavior of the person corresponds to an expected behavior for a state of full consciousness or not (S2, S2′); triggering an alarm if the analysis results in that the detected behavior does not correspond to the expected behavior (S3).

A memory apparatus has a main memory (10) that comprises a plurality of physical blocks of memory locations. The main memory (10), for example a flash memory, supports erasing of at least a physical block at a time. A chain of pointers (72, 75) that ultimately points to pointing information such as a logical address to physical address mapping table is stored in the main memory (10), each pointer (72, 75) being stored in a respective one of the blocks (70, 74), each non-final pointer (72) in the chain pointing to a respective block (74) that contains a next pointer in the chain. On start up of main memory (10) the pointing information is located by following said chain, using the pointers from the main memory. In normal operation direct pointers stored in a RAM are preferably used.

In an example embodiment, an electronic circuit comprises a memory matrix with rows and columns of memory cells. First row conductors are provided for each of the rows. Second row conductors correspond to pairs of rows, each successive row forming a respective pair with a preceding one of the rows, so that each pair overlaps with one row of the next pair. Column conductors are provided for each of the columns. Each of the memory cells comprises an access transistor, a node and a first and a second resistive memory element. The access transistor has a control electrode coupled to the first row conductor of the row of the memory cell, a main current channel coupled between the column conductor for the column of the memory cell and the node. The first and second the resistive memory element are coupled between the node and the second row conductors for the pairs of rows to which the memory cell belongs.

Method for writing a label on a recordable record carrier (1), the record carrier adhering to a predefined, standardized condition with respect to a physical parameter. The method retrieves label information, parameter information on the physical parameter, which parameter information is of a higher precision than the precision of the physical parameter mentioned in the pre-defined, standardized condition (22), and writing the label information on the optical disc using the parameter information (26). The invention further relates to a device for performing the method. Retrieving parameter information on the physical parameter with a higher precision than the precision of the physical parameter mentioned in the pre-defined, standardized condition enables writing such a label without a significant distortion in the label.

The present invention relates to a write controller for a memory with a plurality of non-volatile storage cells, a read controller for a memory with a plurality of nonvolatile storage cells, to a combined write/read controller, to a solid state device comprising a memory with a plurality of non-volatile storage cells, a programmer device for writing a binary code to a non-volatile memory, to a method for writing data comprising at least one input bit to a memory having non-volatile storage cells, and to a method for controlling the integrity of data comprising at least one input bit stored in non-volatile storage cells of a memory. The basic concept of the present invention is to extend information stored in a non-volatile memory by at least one checking bit. The checking bit is allocated to one code bit, or to each of a plurality of code bits.
摘要:
In order to create a record carrier having a side-channel which cannot be copied with a channel-bit recorder, the record carrier (1) has a modulated spiral. By modulating one or more of the spiral parameters, like the channel bit length or the track pitch, a side-channel is created. If a record carrier having such a side-channel is copied using a channel-bit recorder, the information present in the side-channel is lost. The number of bits to be stored in the modulated spiral can be selected as desired; also the way in which the bits are present can be selected; the bits can e.g. can be stored in different bands (A,B,C,D) present on the record carrier, in which band the spiral parameter modulated can be kept constant.
