IPC: G02F1/35
Filed: 1990-04-25
Granted: 1996-07-02
Abstract: A laser amplifier package comprises two laser amplifiers (1 and 2) coupled via two lenses (5 and 6) and an optical isolator (7). The first and second laser amplifiers may both be run as amplifiers to give an overall improved gain and reduced residual facet reflectivity. The first amplifier may be run as a pulse source as part of an LEC or gain switched DFB laser assembly. Pulses generated to be, or compressed to, near transform limited enable the output from the package to be optical solitons. The second laser amplifier may be switched to provide modulation.

Title: Surgical drill guide
Inventor: TROTT A FRANK
IPC: A61B17/17
Filed: 1992-06-23
Granted: 2003-01-28
Abstract: A drill guide is disclosed in which a cylindrical guide tube is secured to a handle so that it may not be easily longitudinally moved in either direction without the user engaging a thumb activated locking mechanism. The cylindrical guide tube passes through a conically tapered cylindrical bore within the drill guide handle and a similarly tapered split collet is interposed concentrically between the exterior of the cylindrical guide tube and the interior of the bore. The collet is provided with a plurality of longitudinally extending lobes which are sufficiently resilient that movement of the collet to its proximal-most position causes the lobes to squeeze inwardly against the cylindrical guide tube.      Frictional engagement between the collet lobes and the guide tube prevents the latter from moving until the collet is moved distally to release pressure on the lobes. The collet is normally biased proximally by a leaf spring attached to the drill guide handle and a thumb activated lever is provided to move the leaf spring distally to release pressure on the lobes and unlock the cylindrical guide tube.

Abstract: A pulse-frequency analyzing monitor which is provided with an optical sensor and which is intended for measuring photo-plethysmographically the blood circulation of a subject, such as a body part of a human being or an animal, includes a light source; preferably a light-emitting diode for infrared light, fibre optics, a detector unit for detecting the alternating voltage, or AC-component of a generated PPG-signal for the purpose of determining the heart frequency of the subject, an electronic ampli-fying unit and a presentation unit, for instance an oscilloscope of a display unit. The apparatus also includes means for separat-ing from the detected PPG-signal a signal component which indicates the respiration frequency of the subject. The PPG-signal is coupled to a filter, preferably a digital filter, which enables limit frequencies and the degree of amplification to be set. The digital filter may be a component of a microprocessor which is able to eliminate disturbances, for instance disturbances emanating from 50 Hz stray light, in addition to separating signals concerning the heart and respiration frequency of the subjet. The invention al-so relates to a method of carrying out such photoplethysomographic measuring processes.

Abstract: Abstract of the Disclosure A primary valve orifice (26) divides a check valve cavity into first and second portions (4, 6).  A valve member (34) closes the orifice (26) in response to higher pressure in the first portion (4) and is unseated to open orifice (26)  in response to higher pressure in the second portion (6).   An axial passageway (44) extends through the valve member (34). A control rod (50) extends into the cavity (4, 6) and through the passageway (44).  The rod (50) carries a secondary valve plug (52) that is biased by a spring (60) to close one end of the passageway (44), and a pull block (78) that engages the opposite end of the valve member (34).  A stem (40) extends from the valve plug portion (36) of the valve member (34) through the orifice (26) and is telescopically received in a sleeve (62).   The control rod (50) is pulled to cause the secondary valve plug (52) to unseat and the pull block (78) to engage the sleeve (62).   This opens the passageway (44) to equalize pressure on the two ends of the valve member (34). Further movement of the control rod (50) moves the valve member (34) and sleeve (62) as a unit to open the orifice (26).  The sleeve (62) may be omitted, with the pull block (78) directly engaging the valve member (34).

Abstract: A radio receiver directly digitizes the phase of an intermediate frequency (IF) signal with a desired resolution The frequency of the reference oscillator (503) in the direct phase digitizer (403) is reduced when compared to the frequency previously required for the same resolution. The reduction in the reference oscillator frequency is accomplished by differentiating between IF zero-crossings that occur during the first half of a reference oscillator cycle and zero-crossings which occur during the second half of the reference oscillator cycle. The apparatus utilizes 2 zero-crossing detectors (503, 505), the first zero-crossing detector (503) is driven by a positive edge of the reference oscillator signal and the second zero-crossing detector (505) is driven by a negative edge of the reference oscillator signal. Depending upon the alignment of the negative edge zero-crossing indicator and the positive edge zero-crossing indicator, the N-bit phase signal is modified or shifted by one-half a phase sector.
