Filed: 1994-08-12
Granted: 2001-02-20
Abstract: A system for detecting the presence of bacterial growth in a plurality of sample vials incorporates a single test station moveable along each of the plurality of sample vials. In one embodiment, the sensor station is movably mounted on a rod, and that rod is movably mounted on a pair of spaced rods. The rod which carries the test station may move along the spaced rods to change the location of the test station in a first dimension and the test station is moveable along its rod to change location in a second dimension. In this way, the test station may be moved through two dimensions to move serially to the location of each of the plurality of sample vials. In another aspect of this invention, a bar code is associated with each of the sample vials, and the test station makes a reading of that bar code concurrent with a determination being made as to whether there is any bacterial growth in the sample vial. In this way, it is ensured that the results of the evaluation of whether bacterial growth is ongoing will be associated with the proper sample vial. 1n a third aspect of this invention, the sample vial incorporates a plurality of distinct types of bacterial sensors. Thus, the advantages of each of several types of bacterial sensors may be incorporated into a single sample vial.

Abstract: Adaptive compressive gain and level de-pendent spectral shaping circuitry for a hearing aid include a microphone to produce an input signal and a plurality of channels connected to a common circuit output (102). Each channel has a preset frequency response. Each channel includes a filter (F1, F2, F3, F4) with a preset frequency response to receive the input signal (12) and to produce a filtered signal, a channel amplifier to amplify the filtered signal to pro-duce a channel output signal, a threshold regis-ter (34) to establish a channel threshold level, and a gain circuit (24). The gain circuit in-creases the gain of the channel amplifier when the channel output signal falls below the chan-nel threshold level and decreases the gain of the channel amplifier when the channel output signal rises above the channel threshold level. A transducer produces sound in response to the signal passed by the common circuit output.

Abstract: STM traffic, e.g. voice and video telephony (VT), as well as packet mode (e.g. ATM) traffic, e.g. broadcast digital video, interactive television, and data, are transmitted via a multiple access broadband fiber/coaxial cable network. Customer premises equipment (CPE) at stations, and a bandwidth controller, which may be at a head end or central office, with which all stations communicate, work together to adapt to the changing demands of the traffic mix, and efficiently allocate bandwidth to a variety of bursty and isochronous traffic sources. The bandwidth allocation defines two types of time slots, STM and ATM, and divides each frame into two corresponding STM and ATM regions. The boundary between the regions can be changed dynamically. A contention access signaling channel is provided in the STM region, for call control and set-up requests. Within the STM region, the time slots can be of variable length and be allocated on a per call basis; the length of the time slots is proportional to the bandwidth requirement of STM calls. Within the ATM region, the time slots are of fixed length, each capable of accommodating one ATM cell. Further, the fixed length ATM time slots may be reserved for a particular user for the duration of a call, or may be shared through a contention process. At least one contention ATM time slot is always made available for signaling messages related to ATM call control and set-up requests. The downstream time frame is structured in a similar manner, but includes an additional MAP (slot allocation mapping) field to transmit to the stations ATM time slot allocation and status information for time slots in the upstream channel.

Abstract: A non-refillable valve for a pressurized container which includes a unidirectional stepped valve housing within which a freestanding blocking element is housed.  The blocking element is preferably a reversible, symmetrical check that integrally includes stop means for preventing the return of said blocking element to an initial location after it has been moved to a final location that activates the one way characteristic feature of a non-refillable valve (where activation is designed to take place after initially charging of the container).  Further aspects of the invention relate to blocking elements (checks) per se which are suitable for use in non-refillable valves.  In particular, blocking elements that are easy to manufacture and install, blocking elements that possess a degree of rigidity which enhances the check's ability to function as a freestanding element once inserted into a valve housing, and blocking elements which inherently reduce the risk of false check engagement during the valve assembly process, are all contemplated by the present invention.  Other aspects of the invention relate to dual purpose manufacturing processes that use a single basic valve design to enable both refillable and non-refillable valves to be manufactured; and relate to products of the aforementioned processes.

Granted: 1999-04-20
Abstract: A method is described for completing calls to wireless communications customers.A database is queried to determine whether to bill the calling party or the called party for communication charges (e.g., airtime charges) associated with the wireless communication service. When the query indicates that the calling party is to be billed for those communications charges, a telecommunications switch which received the call from the calling party is instructed to record information to be used in billing the calling party for the charges. At the same time, the wireless switch that normally would bill the called party for the charges is instructed to suppress billing of the called party for the charges. The billing instruction is sent to the wireless switch in a signaling message using a message parameter that is unaffected by intermediate (e.g., local exchange carrier) switches.

Abstract: A receiver for soft decision and decoding for deriving an appropriate soft-decision value so as to reduce the error rate at the output of a decoder such as a Viterbi decoder. A length V of continuous transmission sequences possible to be generated is set greater than a memory length L of a channel (V>L). By providing branch metric producing circuits as many as 2N (N=2 V) and add/compare/select apparatus (ACS  apparatus) of as many as N for respective states corresponding to combinations of transmission sequence data of V, the accuracy of a soft-decision value is enhanced. Further, a soft-decision value producing circuit performs a process not based on path metrics but based on survivor metrics. This allows a digital signal processor to easily perform the process.

Abstract: A direct QAM modulator for generating a high power  QAM  modulated  signal  at  microwave  frequencies comprises a hybrid to create the required RF signals for I and Q paths.  In each path, a rat-race coupler is used to get  the  in  phase  and  out  of  phase  RF  signal.    The subsequent circuit blocks in each path consist of a single pole double throw switch (SPDT) switched by the polarity of the incoming data, a reflection attenuator, implemented by using forward biased pin diode terminations and controlled by the absolute values of the baseband pulse amplitude modulation (PAM) signal, and a variable reflection phase shifter  to  adjust  for  the  phase  error.    To  realize modulated  signal  filtering  and  to  compensate  for  the nonlinearities, a combined prefiltering and predistortion block is used to shape the baseband PAM signal in each path.  Finally, a power combiner is used to combine signals from the two paths into one high power QAM modulated and filtered output signal at microwave frequency.
