Patent EP-0650075-A2 (EP)
Inventor: LEWIS JUDITH T
IPC: A61B17/00
Filed: 1994-10-21
Abstract: In a coordinate system defined by a coordinate space digitizer, the location of an implanted symmetric object may automatically be determined based on differences between the characteristic acoustic impedances of at least a portion of an implanted object and one or more materials surrounding that object. An A-mode ultrasound transducer may be attached to a coordinate space digitizer or pointing device such that an attached computer tracks the position and orientation of the ultrasound transducer. The reflected radio-frequency (rf) ultrasound signals may automatically be analyzed along with the transducer position and orientation corresponding to each received rf signal to detect the position of the implanted object. The time delay between received ultrasound echoes is used to compute the depth of the object from the transducer. This allows for an accurate determination of the three-dimensional coordinates of the implanted object.

Abstract: An article 1 to be prevented from forgery previously contains an optical semiconductor, the mixing ratio of which is predetermined. Under the condition that a light source 6 is turned off, microwaves are emitted to the article 1 to be prevented from forgery through a feed phone 5. These microwaves are reflected on the article 1 to be prevented from forgery and supplied to a receiving section 8 through a feed phone 7, so that the receiving level of the microwaves can be measured. Next, the light source 6 is turned on, and the receiving level of the microwaves is measured in the same manner. When an optical semiconductor is irradiated with rays of light, it is excited, so that the microwave reflection factor is enhanced. Accordingly, the receiving level in the case where the light source 6 is turned on is higher than the receiving level in the case where the light source 6 is turned off.

Abstract: A method of producing, on a physical medium, a gradient tonal representation of an image and a printhead for producing the same. An input image is divided into first and second regions. First, continuously variable intensity level, continuous tone and second, discretely variable intensity level, half-tone portions of the representation which respectively correspond to the first and second regions of the image are then printed by depositing selected quantities of ink on the first and second portions of the physical medium such that each pixel thereof has an ink intensity level corresponding to the image intensity level for the corresponding one of the pixels of the first region of the image. The ink is deposited on the second portion of the physical medium by depositing a spot of ink having a first diameter on selected ones of the pixels of the second portion, depositing a spot of ink having a second diameter on others of the pixels of the second portion and depositing no ink on still others of the pixels of the second portion such that the second portion of the representation has the desired ink intensity level. The color of the ink ejected may be black, in which case, the gradient tonal representation produced thereby shall be a gray scale representation, or other color such as yellow, cyan or magenta.

Abstract: An improved gamma camera system comprises a circuit for performing digital dynamic compression wherein the circuit is readily modifiable to accept different compression procedures and the input and output signals are in digital form. The system further includes a photomultiplier tube (PMT) channel amplification integration circuit having multiple separate and independently triggerable integrators. In addition, the system comprises circuitry for generating spatially variant photomultiplier cluster based on a peak photomultiplier and for generating spatially variant weights for photomultipliers of the cluster depending on a cluster type signal. Further, the system includes a system for correcting and maintaining the baseline offset signal value of a PMT channel of a scintillation detector at a predetermined value. The correction system utilizes an event driven mode wherein the correction is performed based on detected gamma interactions and a second mode, software driven correction, wherein false triggers are inserted into the processing logic to initiate sampling of the baseline offset signal value and "simulate" gamma interactions. The system further comprises an automatic gain calibration system for PMTs operable during periods when a collimator is installed to the scintillation detector. The system calibrates PMTs located along the periphery of the detector having surfaces that are partially or totally obscured by the solid lead edge regions of the installed collimator and adjusts the preamplification gain associated with each channel to maintain the effective gain of each PMT in response to long term variations in the characteristic gain of each PMT.

Abstract: An audio mixing console provides for a selected group of channels to be assigned to a bank of channel controls for a channel function (e.g., a solo mode) with a global function indicator for indicating that the predetermined channel function has been selected for at least one channel. A global function cancel button for cancelling the channel function in all channels is provided. Various solo modes can be selected. A logic button includes a button member moveable between a raised position and a depressed position, a switch contact open in the raised position and closed in the depressed position and a logical latch (e.g, software-implemented) responsive to a first closing of the switch on a first depression of the button to change from an inactive state to an active state and to a second opening of the switch on a second release of the button to change from the active state to the inactive state. An automation mode controller is operable, in a first pass, to store on-going switch timings at which the user operable control is switched from off to on and off-going switch timings at which the switch is switched from on to off for automatically reproducing the control switchings in a subsequent pass, the automation mode controller being operable in a subsequent pass selectively to change the on-going and/or off-going switch changes by overlapping switch timings. With two series connected variable gain controls in a signal processing channel a second gain is made dependent upon the first gain to cancel out changes of the first gain. A user operable control is provided to select the signal source for the control room loudspeakers. Operation of the loudspeaker source selector function connects the loudspeakers permanently to the main stereo output bus only, allowing the operator to monitor AFL and PFL functions privately using headphones, while the complete mix is audible on the loudspeakers.

Abstract: An electrosurgical system including an electrode assembly having two electrodes for use immersed in an electrically conductive fluid has a generator with control circuitry for rapidly reducing the delivered radio frequency output power by at least 50% within approximately 100µs, corresponding to the time needed for a few cycles of the peak radio frequency output voltage to reach a pre determined threshold limit. In this way, tissue coagulation can be performed in, for example, saline without significant steam generation. 
     The same peak voltage limitation technique is used in a tissue vaporization or cutting mode to limit the size of the steam pocket at the electrodes and to avoid electrode burning. 
     The output power reduction is abtained by "on time control" (70) by producing a signal synchronous with the RF oscillator, thereby reducing progresseively the "conduction state" of the gate (80) which connects the power supply with the oscillator. Switch mode power supply (66) can itself vary its output voltage as a function of signal (66) from the controller (72), the speed of variation however will be much slower than the one produced by "ON" time control mechanism.

Abstract: A magnetic actuator arrangement, principally for a vacuum switching apparatus, employs, instead of precision ball-joint bearings (16) supporting the armature (14), simple bushes (40) with an inside diameter deliberately greater than the outside diameter of the armature spindle (15), such that the armature (14) is a loose fit inside the bushes (40). The effect of this is to enable the armature (14) to make non-rotational movements in the plane perpendicular to the spindle (15), and so automatically to assume a properly seated position with respect to the pole pieces (21, 22) of the magnets (10, 11) when the latter are energised, thereby eliminating an undesirable vibration at the magnet-armature interface. With conventional bearings having negligible play, this can only be done after time-consuming manual adjustment of the bearing locations by skilled technical personnel.

Abstract: Es sind zwei Parallelreglerstufen mit jeweils einem Transistor (T1 bzw. T2) vorgesehen. Der Transistor (T2) ist Teil der indirekten Parallelreglerstufe und wirkt direkt am Gleichrichter. Er kann relativ hohe Ströme aufnehmen und ist dadurch relativ langsam. Der Transistor (T1) ist Teil der direkten Reglerstufe und wirkt parallel zum Stützkondensator. Er braucht infolge der Grobregelung durch den Transistor (T2) nur geringe Stöme aufnehmen und kann daher ein sehr rasches Regelverhalten haben. Durch die Grobregelung von Transistor (T2) bricht die Wechselspannung an den Antennenanschlüssen (LA und LB) rasch zusammen, wenn das HF-Signal unterbrochen wird; dadurch kann die Übertragungsrate bei einer Pausenabstandsmodulation erhöht werden. Auch werden statische Aufladungen vom Transistor (T2) abgeleitet, so daß diesbezüglich keine zusätzlichen Schutzschaltungen notwendig sind.
