Abstract: A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening.  The opening defines upper and lower ends, and the lower end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment.  The lower end of the locking pin is constructed to engage the tool attachment when the locking pin is positioned in an engaging position and to release the tool attachment when the locking pin is moved to a release position.  An actuating element is movably positioned on the drive stud, and the actuating element is coupled to the locking pin to move the locking pin from the engaging to the release position as the actuating element moves along the longitudinal axis.  An anti-rotation key is positioned between the actuating element and the drive stud to slide in a groove formed in either the actuating element or the drive stud and thereby to limit rotation of the actuating element and associated side loading of the locking pin.  If desired, a resilient retaining element can be positioned in a recess in either the actuating element or the drive stud to limit movement of the actuating element relative to the drive stud along the longitudinal axis.

Abstract: Various optical amplifier configurations are disclosed.  In one configuration, an optical amplifier provides an amplified output signal through use of a pumping device.  The output signal is split to an output and a feedback input.  The feedback signal is converted to a current which is  sensed by a controller.  The controller adjusts the amount of current to the pumping device in various instances.  In one instance, the current is controlled to prevent overdriving the pumping device.  In another instance, the current is controlled to maintain the output signal at a substantially constant level.  In another configuration, the optical amplifier is coupled to a ratio computation block which measures the operating efficiency of the pumping device. Additional components detect an undesirable efficiency and provide a warning of the same.

Title: Personal mobile communication system
Inventor: FOLADARE MARK JEFFREY
IPC: H04W84/02
Filed: 1995-04-26
Granted: 1999-01-19
Abstract: We have recognized that in the prior art, to insure that there is at least some communication between the calling and called parties, when the called party is unavailable to take a call, the calling party may be connected to an alternate destination, e.g., a voice messaging system, and the caller's telephone call is considered completed. If the called party thereafter becomes available, the called party is not connected to the caller's telephone call. However, in accordance with the principles of the invention, this problem is overcome by, in response to receipt of an indication that the called party is available for a caller's telephone call after the caller's telephone call has already been connected to an alternate destination, a) disconnecting the caller's telephone call from the alternate destination and, instead, b) connecting it the called party, thus interrupting the connection between the caller and the alternate destination. Optionally, a tone or announcement may be supplied to the caller to indicate that the called party will now be connected "live" to the caller.

Abstract: The initial steps in photosynthesis are the conversion of light energy into chemical energy. This conversion is performed by the multisubunit protein-pigment complexes of the thylakoid membranes. Oxygen-evolving photosystems contain photosystem I (PSI) and photosystem II (PSII), which act in tandem. In PSII, the majority of light-adsorbing chlorophylls are attached to LHCII, the light harvesting complex associated with this photosystem. LHCII is the most abundant member of the family of chlorophyll a/b binding (CAB) proteins. A gene encoding a type I chlorophyll a/b binding protein of LHCII (ICABPSII) has been cloned from Brassica napus L. An anti-sense RNA of this gene has been used to reduce the amount of chlorophyll a/b binding protein and thus reduce the amount of chlorophyll in the resulting transgenic plants. By using "site"  specific promoters the reduction of chlorophyll can be targeted to specific organelles in the transgenic plant and thus can be used to reduce the green colour at these sites. Thus it is possible to use the anti-sense RNA of a chlorophyll a/b binding protein as a means for degreening, for example fruits, seeds or floral parts in transgenic plants.

Abstract: An rms value of a sum signal series x = en + vn calculated by adding a noise series to an error signal series of a known signal series and an unknown signal series, is calculated by an rms calculator.   By means of an amplitude controller, x is output as is when ¦x¦ is smaller than a threshold value A proportional to the rms value.          When ¦x¦ is greater than the threshold value A, a product signal calculated by multiplying the polarity of x with the threshold value is output.  Utilizing the output of the amplitude controller, respective tap weights of filter is corrected to generate be tap weights Ck(n). By this, switching  control  between  a  probability  gradient  LMS algorithm ( LA ) and a probability gradient sign algorithm ( SA ) can be performed smoothly.   Thus,  an adaptively controlled filter having an advantage of small residual error and fast convergence of LA and an advantage of satisfactory strength against disturbance, such as burst noise or so forth of SA, can be obtained.

Abstract: A switching and purging mechanism is disclosed for controlling flow of gas within a twin tower gas drying system.  The drying system filters unpurified gas to supply purified gas to a pneumatic system with a purge percentage for purging moisture previously retained.  The mechanism includes a valve body, first and second pistons, and a control means.  The body defines first and second bores, first and second supply passages, first and second output ports, and first and second purge ports.  Through the control means, the first piston occupies a supply position while the second piston occupies a purge position and vice versa.          When the first piston occupies the supply position, unpurified gas flows from the first passage through the first bore through the first output port and communication between the first output port and the first purge port ceases.  When the first piston occupies the purge position, remoisturized gas flows from the first output port through the first bore through the first purge port and communication between the first passage and the first output port ceases.  When the second piston occupies the supply position, unpurified gas flows from the second passage through the second bore through the second output port and communication between the second output port and the second purge port ceases.        When the second piston occupies the purge position, remoisturized gas flows from the second output port through the second bore to the second purge port and communication between the second passage and the second output port ceases.
