The output device receives this signal from the controller that a given sound produced in the ambient environment has been captured and produces a notification signal thereby notifying in real-time the user of the given captured sound.

Method and device for providing high data rate for a serial peripheral interface

An improved high performance scheme is provided with a serial peripheral interface (SPI) to enable microcontroller-based products and other components and devices to achieve a higher serial transmit and receive data rate. An exemplary technique utilizes a CPU and an SPI having a circular FIFO structure. To prevent the memory traffic associated with any SPI accesses from conflicting with other CPU memory accesses, the technique utilizes cycle stealing direct memory access techniques for SPI data transfers with the memory. During a CPU read/write sequence, data is read/written from/to the memory through a virtual special function register (SFR). Once the virtual SFR access is detected, all accesses are redirected to the circular FIFO buffer memory, with no additional pipelining necessary. The CPU pointers can suitably increment as appropriately controlled by hardware. In addition, once an SPI transmit/receive request is made, data communication can be established between the transmit/receive buffer and the memory. To avoid structural hazard, the transmit/receive request can be suitably pipelined until the next available clock phase, for example, within one instruction cycle. As a result, for a 4 Mhz clock rate, the technique can enable a significantly higher data transfer rate, e.g., at 250 Kbytes per second, an improvement of almost twenty times the prior art data rates. The high performance technique also avoids the firmware overhead with minimum hardware control cost. For example, compared to the hardware approach using deeper buffer structures, e.g., with FIFO buffers implemented using flip-flop devices, the exemplary techniques utilize memory, e.g., dynamic or static random access memory (DRAM or SRAM) with direct memory access (DMA).

Electrical connector device securable to metal member

An electrical connector device comprises a disc-like connector element having a hole therethrough. From a face thereof substantially hard contact means projects outwardly, in the form of an annular ridge which tapers outwardly to a sharp or rounded edge and which is concentric to the hole and radially spaced therefrom. An elastically deformable sealing element overlies said face of the connector element and, in the unused device, embeds the contact means. Tightening of a screw through the hole, to secure the device to an object member, forces the contact means through the sealing element and partway into the object member. The annular electrical connection thus formed is durably sealed by the compressed sealing member.

Method and apparatus for separating biological molecules

A system for separating biological molecules includes a chip ( 10 ) on which there is an electrophoresis separation microchannel ( 16 ). At the start of the channel there is an isoelectric focusing section ( 14 ) containing a gel having a pH gradient. Molecules to be separated are placed in the focusing section ( 14 ) and move to an equilibrium position under the influence of an electric field. The electrophoretic state of the molecules is then changed, and a high voltage potential applied across the entire length of the focusing and separation sections. The molecules migrate under the influence of the electric field from the focusing section into the separation section where their position and velocity are tracked. From a knowledge of position and velocity, a user can determine both charge/mass ratio and isoelectric equilibrium point for each molecule. The gels can be replicated in the chip to allow parallel analysis, and hence comparisons, to take place.

Panel assembly with a gasket and method for its production

The panel assembly comprises a panel (2) and a gasket (1) adhered to the panel and extending along at least a portion of the periphery. For producing the panel assembly a curable composition is applied either directly or indirectly onto the panel and onto a mould surface (6) onto which the panel has been positioned. When being applied on the mould surface, the curable composition has a dynamic viscosity which is lower than the dynamic viscosity of extrusion materials. In this way, a better surface quality can be achieved without having to exert a high pressure onto the curable composition. In contrast to the known RIM processes, the curable composition is not injected in a closed mould but is applied onto an open mould surface by means of an applicator device (9) moving along at least said portion of the periphery of the panel (2). In this way, cheaper moulds can be used and in particular moulds made of a soft, resilient material (8).
