摘要:
A television signals receiver for receives and stores television signals encoded at a variable data rate. Time information is generated based on the time of receipt of the signals that defines the duration of the television signals when output in decompressed form at a substantially constant data rate. The received signals are then written to a file on a hard disk (13) in received order together with the time information. The time information of signals stored in the file is monitored and old signals are deleted from the file such that the file stores signals corresponding to a predetermined period of time.

A fluid transfer apparatus includes a fluid transfer probe, a fluid level detection system, and a tip detection system. The fluid level detection system is configured to detect contact by the fluid transfer probe with a fluid surface within a receptacle from a signal based on the capacitance of the fluid transfer probe. The tip detection system is configured to detect the presence or absence of a tip at a distal end of the fluid transfer probe from a signal based on the capacitance of the fluid transfer probe.

A structure (10) for holding sample-containing receptacles includes a cover (40) with holes formed therein through which the receptacles can be accessed with a substance transfer mechanism, such as a robotic pipettor. When the transfer mechanism is inserted into and then withdrawn from a receptacle, a string of viscous material may be suspended from the mechanism. A viscous string removal element (44) adjacent each opening (42) engages the string of viscous material and dislodges the string from the mechanism when the mechanism moves in a prescribed path with respect to the removal element. A sample rack configured to hold receptacles and to be inserted into the structure below the cover includes a sample rack having receptacle-receiving pockets, each with a resilient element and a positioning feature for holding receptacles of varying sizes in a predetermined position within the receptacle receiving pocket, and a cover including features for preventing a receptacle from being pulled out of its receptacle-receiving pocket when the transfer mechanism is withdrawn from the receptacle.

To minimize cross talk in systems and methods for detecting two or more different optical signals emitted from each of a plurality of reaction receptacles, an excitation signal associated with each of the optical signals has a known excitation frequency, and any detected signal having a frequency that is inconsistent with the excitation frequency is discarded. The receptacles are moved relative to optical sensors configured to detect each unique optical signal from an associated receptacle, and to further minimize cross talk, the optical sensors are arranged so that only one reaction receptacle at a time is in a signal detecting position with respect to one of its associated optical sensors, and the optical sensors are grouped by the optical signal they are configured to detect so that a first optical signal is detected from each of the reaction receptacles before a second optical signal is detected from the reaction receptacles.

It is an object of the present invention to provide a cutting machine capable of keeping an angle of a cutting edge constant. A support block 14 is provided with two arms 14a, 14b which are spaced at a certain angle, and the arms 14a, 14b have rotation shafts 12a, 13a of rotary whetstones 12, 13, respectively, extending upright from the vicinities of the front ends thereof. The rotary whetstones 12, 13 has, at front ends thereof, flat surfaces 12b, 13b perpendicular to the rotation shafts 12a, 13a to grind the one side 11b and the other side 11c of the cutting edge 11a of the cutting blade 11, respectively. The whetstone holding mechanism 15 can be moved linearly along the guide shaft 16 and can change over grinding states in which the flat surfaces 12b, 13b of the rotary whetstones 12, 13 into contact with the one side 11b or the other side 11c of the cutting blade 11. Even when the grinding progresses, since parallelism between the flat surfaces 12b, 13b and the one side 11b and the other side 11c of the cutting blade 11, so that the angle of the cutting edge is kept constant.
摘要:
A receiver for television signals is arranged to receive video signals comprising video data and information data. The receiver is arranged to respond to viewer operation of a control device. The receiver includes a processor for processing selected information data to convert the same into signals representative thereof for output to a television in combination with the video signals. The receiver is arranged to respond to the information data to output for display data derived from said image data and said information data and representing an inter-active image. The receiver is responsive to viewer manipulation of the control device to vary the interactive image and to establish a telecommunications link to a remote site for on-line interaction via the interactive image between the viewer and the remote site. The interactive image may form part of an interactive services interface comprising a broadcast entry level and plural broadcast interactive levels. The interactive services interface may comprise one or more on-line interactive levels entered from one of the broadcast interactive levels for establishing an on-line connection with a remote site.

A computer-implemented method and system for negotiating the purchase of goods and/or services by customers utilizes a simulated human merchant having predefined behavioral attributes. An algorithm representing behavioral attributes of a simulated human merchant is used to receive customer input data relating to particular goods and/or services desired to be purchased. The customer input data is processed to generate merchant responses to the customer input data, and the sale of goods and/or services are agreed to at a particular price as a result of processing of customer replies to merchant responses according to the algorithm.

A container for transport and storage of liquids comprises a pallet and a metal cage of standard dimensions. The container comprises also an inner bag made of plastic material, an outer envelope disposed between the inner bag and the metal cage, and fastened to the metal cage. The inner bag is not fastened to the outer envelope and is configured to be filled to unfold from an empty condition, in which the inner bag is in a flattened and folded configuration to a filled condition, in which the inner bag is in a parallelepipedal and unfolded configuration, having a volume corresponding substantially to the volume of the housing of the cage and being surrounded by the outer envelope and the metal cage.
