Abstract: A method and apparatus is presented for establishing an equivalence between the Hamming branch metric scheme and the Manhattan branch metric scheme. A signal format converter is presented to convert input signal in a first number system such as binary or two's complement, into a second number system. The signal format converter implemented at the input to a Viterbi decoder allows the use of a Viterbi decoder designed for a Manhattan metric sceme in an application where the signals are represented in two's complement. Similarly a Viterbi decoder designed for a Hamming metric scheme can be implemented in an application where the signals are represented in unsigned binary. The signal format converter can be used with both a hard decision Viterbi decoder and a soft decision Viterbi decoder. Where a soft decision Viterbi decoder is used the soft symbol of a Manhattan metric scheme based Viterbi decoder can be converted to an equivalent Hamming soft symbol by taking the two's complement of the absolute value of the accumulated cost difference. Where the Viterbi decoder is based on a Hamming metric scheme, an equivalent Manhattan soft symbol can be obtained by taking the absolute value of the soft symbol decoded output.

Abstract: A passive liquid crystal device (Figure 1) is driven in a multiplexed manner by a strobe signal (STB) applied in succession to a plurality of row electrodes and data signals (DATa, DATb) applied to a plurality of column electrodes. A resultant signal (RESa, RESb) comprising the combination of the strobe and data signals is applied to the pixels in the device. The liquid crystal device is sensitive to the polarity of the resultant signal. Typically a blanking pulse of a first polarity is applied followed by a resultant signal of the opposite polarity. A first data signal (DATa) is intended to change the state of the relevant pixel (SELECT) while a second data signal (DATb) is intended to leave the pixel in the same state (NON-SELECT). According to the invention the resultant signal (RESa, RESb) comprises at least a portion which is substantially continuously varying. This can be achieved by either or both of the strobe and data signals including such a portion or portions. The invention may provide improved performance of the device through maximisation of the torque applied to the molecules of the liquid crystal during the switching process in response to a SELECT resultant (RESa). The invention is particularly applicable to ferroelectric liquid crystal devices (FLCDs).

Abstract: An appliance (10) is provided for installation within the mouth (14) of an
individual (16) to prevent obstruction of the natural airway of the individual and to
enhance natural ventilation during sleep. The appliance is hollow and is
custom-molded to the oral cavity for biasing tissues surrounding the user's natural
airway to keep the airway open. An external positive air supply (20) is also provided
which connects to a tube (22) extending from the appliance and forces air through
the hollow appliance to a rear opening (24) of the appliance in the user's
retroglossal area (26). A sensor (31) provides control information to the positive air
supply by sensing relative pressure in the user's oral cavity. The natural breathing
cycle is thus enhanced but not controlled by the appliance.

solution to form the hollow fiber membrane. The polymer-containing
spinning solution is extruded from the outer
tube of the orifice to form a cylindrical filament having
an inner bore and a core solution is ejected from the inner
tube of the orifice into the inner bore of the filament for
coagulation of the filament. The filament is directly
extruded into the coagulation solution or extruded into air
and then drawn to the coagulation solution. The core
solution is supplemented with a hydrophobic modifier such
as vitamin E and a surfactant and the resulting hollow
fiber membrane contains the hydrophobic modifier on its
inner surface.

Abstract: The present invention is directed to a high speed packet switching network and, in particular to a method and system for minimizing the time to establish a connection between an origin and a destination node. Due to high dynamicity of the traffic on transmission links, it is important to select a routing path according to a fully up-to-date information on all network resources. The simpler approach is to calculate a new path for each new connection request. This solution may be very time consuming because there are as many path selection operations as connection set up operations. On another hand, the calculation of paths based on an exhaustive exploration of the network topology, is a complex operation which may also take an inordinate amount of resources in large networks. Many of connections originated from a network node flow to the same destination network node. It is therefore possible to take a serious benefit in reusing the same already calculated paths for several connections towards the same node.The path calculated at the time the connection is requested is recorded in a Routing Database and updated each time a modification occurs in the network. Furthermore, alternate paths for supporting non-disruptive path switch on failure or preemption, and new paths towards potential destination nodes can be calculated and stored when the connection set up process is idle. These last operations are executed in background with a low processing priority and in absence of connection request.

Abstract: A focusing delay calculation apparatus for real-time digital focusing_
calculates focusing delay times for individual array elements constituting an
array transducer in an ultrasonic imaging system in which a focal point is
varied on the basis of a midpoint algorithm. A delay variable calculator
uses a focusing reference distance, integer focusing delay distances and
decision variables corresponding to an array element at an n- th  focal point
to calculate a delay variable corresponding to the array element at an
(n+1) th  focal point. An updating unit uses the delay variable calculated by
the delay variable calculator to produce the integer focusing delay distance
and the decision variable corresponding to the array element, and then
supplies the produced integer focusing delay distance and decision variable
to the delay variable calculator. The delay variable is represented as a
value having places below a decimal point. Thus, the present invention can
calculate a focusing delay distance represented with accuracy below a
decimal point with respect to a varied focal point. and implements the
calculation of the focusing delay with the addition of simple hardware,
accordingly, the manufacturing cost is low.

Abstract: Branch predictions are adjusted by interrupting a central processing unit (12) and
observing a pending branch instruction. An interrupt is generated using a counter (40),
timer (42), or software-based interrupt (36). The interrupt causes a prediction
adjustment routine to execute, which in turn determines whether a pending branch
instruction will branch. The actual branch behaviour of the branch instruction is
compared to the predicted branch behaviour of the branch instruction, and the prediction
is adjusted accordingly based on the accuracy of the prediction and previous branch
behaviour. After the prediction has been adjusted (if necessary), execution returns to the
program that contains the branch instruction that was evaluated.
