Abstract: The invention provides stronger error correction capability in an error correction encoding/decoding system of a digital mobile telephone or so forth. In a viterbi decoding system at a receiver side, a branch metric is calculated and stored without selecting a path with respect to a plurality of branches corresponding to a parameter having a correlation between frames. Also, utilizing a separately stored parameter value in a previous frame, a transition probability of the parameter value in the current frame is obtained, a metric value of a path is converted and added to an accumulated path metric value up to the previous branch, a comparison of the metric values at various states is performed to select the path having higher likelihood to perform decoding by maximum likelihood decoding.

Title: Conference system with automatic speaker detection and speaker unit for use in the conference system
Inventor: JANSE CORNELIS P
IPC: H04M9/08
Filed: 1993-04-08
Abstract: A conference system comprises speaker units (12) coupled to a central unit. The speaker unit (12) comprises an echo canceller (20) with an adaptive filter (38) having an impulse response of comparatively short duration. In a speech pause of the user of the speaker unit (12) the common listening signal (LS) of the conference system is applied to the loudspeaker (18). Of the sounds then picked up by the microphone (16) only those sounds are compensated which are produced by the loudspeaker (18) and which reach the microphone (16) directly and which reach the microphone (16) indirectly  via  reflections from nearby objects. These sounds have a comparatively short impulse response time and enable a comparatively simple adaptive filter (38) to be used. The other sounds picked up by the microphone (16) reach the microphone (16)  via  reflections from the walls of the conference space in which the conference system is situated. The other sounds have a comparatively long impulse response time. For the purpose of automatic speech detection these other sounds do not require echo cancellation because they are the same for all the speaker units. Automatic speech detection is now effected if the signal strength of the compensated microphone signal (MCCS) produced by the echo canceller (20) exceeds the average signal level of the speaker units.

Abstract: The relative height between two sets of magnetic head groups AT,BT shared for recording and reproduction and mounted on actuators 100A, 100B is adjusted at high accuracy, so that a track of a predetermined track width and track pitch can be formed. In a rotary head type magnetic recording/reproduction apparatus including two sets of magnetic head groups AT and BT of one or a plurality of magnetic heads displaceable in the track width direction by actuators 100A and 100B, a signal which becomes the reference for relative height adjustment of the heads is recorded by one of the magnetic head groups. Then, the magnetic tape is rewound, and the run of the magnetic tape is controlled by one of the magnetic head groups. Under this state, the relative height between the two sets of magnetic head groups is detected by the other magnetic head group, whereby the relative height of the two sets of magnetic head groups is adjusted according to that information.

Abstract: A method for determining whether a particular sample vial has bacterial growth includes the steps of introducing a first light into the sample vial and measuring the intensity of the reemerging light. One then introduces a second light which is different from the first light and has either a different wavelength, or is introduced at a different location than the first light. The reemerging intensity from the second light is also measured. A ratio quantity is calculated based on the two reemerging intensities, and the calculated ratio is compared to expected ratios for both positive and negative samples. It has been found that a comparison of the reemerging light intensities provides a very good indication of whether a particular sample is a positive or negative sample. Various methods and formulas for calculating the ratios may be utilized. Graphs associated with the particular methods and formulas are developed experimentally to allow one to compare a particular calculated ratio value to expected values for positive and negative cultures.

Abstract: A burner block (12) for mounting a burner (14) within a furnace containing a melt to be heated by the burner. The burner block comprises a body (20) having a passageway (22) terminating in a divergent opening (24). The passageway is configured to receive the burner so that the burner is recessed within the divergent opening (24) and a flame (16) produced by the burner is directed out of the divergent opening and over the melt (18). The divergent opening has a lower section (26) angled in a downward direction and the lower section has a reversed step (28) to produce a primary recirculation zone (A) beneath the flame, thereby to draw the flame in a downward direction toward the melt. The reversed step is positioned within the divergent opening so that when the burner is in use, a secondary recirculation zone (B) forms between the opening and the melt and further draws the flame in the downward direction toward the melt. The height of this secondary recirculation zone will vary with the height of the melt within the furnace to produce a self adjustment of the flame toward the melt. In another aspect, the present invention relates to a furnace incorporating the aforesaid burner block, a burner positioned within the burner block and a melt.
