IPC: H04N19/50
Filed: 1998-03-16
Abstract: A block matching method includes the steps of selecting a reference block Bm from a current frame Fn (500), determining the center point of a target window Wm for a previous frame F n-1  to be the center point (X n ,Y n ) of the reference block Bm (505), obtaining a motion vector (Dxn, Dyn) for the reference block Bm, using the target window (510), selecting the next reference block B m+1  the center point coordinates of which are (X n+1 , Yn) in the current frame Fn (515), determining whether the current frame Fn has a complicated motion (520), obtaining a motion vector value using a predetermined general block matching method, when the current frame Fn has a complicated motion (525), when the current frame Fn does not have a complicated motion (530), determining the center of a target window WW m+1  for B m+1  in the previous frame F n-1 , to be (X n+1 +Dxn, Yn+Dyn), determining whether the target window WW m+1  is within the boundary of the previous frame F n-1  (535), and obtaining a motion vector (DDxn+1, DDYn) (545) after limiting the center of the target window WW m+1  to be within the boundary of the previous frame F n-1  if necessary.

Title: Hardware high-level synthesis including branch instructions
Inventor: NISHIDA KOICHI
IPC: G06F17/50
Filed: 1999-02-23
Abstract: A circuit hardware synthesis method comprises converting a behavioural description including an execution control branch instruction into a control flow graph (CFG), converting the CFG into a control data flow graph (CDFG), performing scheduling according to the CDFG and performing allocating according to the result of scheduling. The control branch instruction may be a goto statement, and the C programming language may be used for the behavioural description. In this case, the branch instruction may be the C switch statement. For a goto or switch statement, the behavioural description is divided into partial descriptions separated by either an if-goto statement or a sub-statement of the switch statement. Each partial description is represented by a partial CFG, and a branch node is generated corresponding to either the if-goto statement or a conditional expression or an if-break expression of the switch statement. Control flow branches are branched, and finally a merge node is generated corresponding to either a jump destination label or the case constant or sub-statement end point of the switch statement, and control flow branches are merged.

Title: An aldehyde-free sterilant and disinfectant based on a peroxide source in powder or kit form for mixing and/or diluting
Inventor: GREEN BRUCE PHILIP
IPC: A01N37/16
Filed: 1999-05-06
Abstract: A formulation is provided as a concentrate for producing a biocidally active solution. The formulation comprises a water soluble oxidant generator-peroxide source (eg hydrogen peroxide, sodium perborate or potassium peroxy monosulphate) and is in the form of:<BR> either a single-pack powder that is diluted and dissolved to produce the biocidally active solution<BR> or a twin-pack liquid or liquid-and-solid formulation which (when the components are mixed or are diluted, mixed and dissolved) provide the biocidally active solution. The formulation may optionally comprise a buffer (eg citric acid), an oxidant stable surfactant, a metal sequesterant (eg ethylenediamine tetramethylphosphonate), a peroxide reactant/trigger, a corrosion inhibitor, a colour, a perfume or an indicator which improves effective hygiene performance. Tetraacetyl ethylene diamine (TAED) may be included as a potentiating ingredient which, under slightly alkali conditions of a buffered solution, is activated to produce a very effective low temperature biocide, by reacting with peroxide anions to produce peracetic anions. This combination of hydrogen peroxide, peracetic acid and peracetic anions is synergistic and produces a rapidly biocidal and sporicidal solution with a very broad spectrum of activity. It may be used as a sterilant/sanitiser in medical, veterinary and food establishments (eg sterilising medical and dental instruments).

Title: Optical ultrasonic measurement
Inventor: ASTILL ANDREW GRAHAM
IPC: G01H9/00
Filed: 1999-12-03
Abstract: An apparatus and method are provided for detecting ultrasonic waves at a surface of an object 12 at two separate locations (A and B). A light beam from a single continuous laser source (20) is split into two out-going beams (1, 2). These beams are incident at the two separate locations (A and B), and the resulting reflected beams are then incident on a common interferometric detector (38) and a photodetector (40). These returning reflected beams are orthogonally polarised. The signals from the photodetector (40) represent a superposition of the surface movements at the two locations. Hence the time for an ultrasonic wave to propagate from one location (B) to the other (A) can be measured, this measurement being unaffected by any displacements of the source (16) of the ultrasonic waves.
Patent HU-T71356-A (HU)
Title: Method for immobilization or extirpation of larvae swimming in water and electric trap for carrying out said method
Inventor: OSTLIE LARS STEINAR
IPC: H05C1/02
Filed: 1992-04-03
Abstract: A trap for swimming larvae in fresh water is constituted by two capacitor plates for influencing a mass of fresh water between the plates. An alternating current flowing in the interior of the larvae is able to kill the larvae, and the power dissipation of the trap is limited substantially thereto, while the effect of heating up the mass of water is avoided, since fresh water is a poor conductor. Therefore, it is sufficient with a voltage generator which supplies a relatively low power, i.e. a relatively high voltage but a limited current. In a method where the trap is used, a concentrated electric power dissipation of an immobilizing or killing magnitude is caused in the interior of the larvae. The interior of the larvae is constituted substantially of an electrically highly conductive liquid, and when an alternating electric field is established in the water between the capacitor plates, there will be an alternating polarization of both water mass and larvae, and an alternating current is caused inside the larvae.
