Title: Cell interval determination apparatus for usage parameter control
Inventor: KAGANOI TERUO
IPC: H04L12/70
Filed: 1996-07-09
Granted: 2001-02-20
Abstract: A cell interval determination apparatus for usage parameter control, includes a counter, a memory, a cell arrival interval check unit, and a control unit.          The counter is incremented every time a cell has arrived in an asynchronous mode to represent a cell arrival time. The memory stores, in units of cell type information, cell information consisting of cell type information included in the cell, the cell arrival time counted by the counter, a cell arrival interval defined value which is set in units of cell type information, and flag information representing a retrieval target/non-retrieval target. The cell arrival interval check unit calculates a time difference between the cell arrival time stored in the memory and the cell arrival time represented by the counter and determines a cell which violates the cell arrival interval defined value stored in the memory. The control unit retrieves, from the memory in accordance with the flag information, cell information having the same cell type information as that extracted from the arriving cell, designates to start the cell arrival interval check unit in accordance with a retrieval result, and stores the cell information associated with the arriving cell in the memory in accordance with the retrieval result and a determination result of the cell arrival interval check unit.

Abstract: A method and apparatus for providing power management functions in a multifunction controller having an embedded microprocessor. An enter sleep mode indication is received in the microprocessor in the form of, for example, a command generated by a host central processing unit or an interrupt indicating a lack of system activity for a predetermined period of time. The clock input to the microprocessor is switched from a first clock source to a second clock source in response to the enter sleep mode indication. The main system supply may then be powered down by the microprocessor. The first clock source is then turned off after expiration of a first predetermined delay. The second clock is subsequently turned off after a second predetermined delay, to thereby place the system and the microprocessor into a sleep mode. While the system and microprocessor are in the sleep mode, an interrupt-handling portion of the microprocessor and a power control logic circuit remain powered off a low-current standby supply. Upon detection of a wake-up event, the second clock source is automatically started and applied to the microprocessor after a predetermined delay. The microprocessor can then process the wake-up event indicator, and if necessary power up the system and re-connect itself to the first clock source.

Abstract: An improved process for removing protein deposits from contact lenses with a single solution is described.  The process utilizes the cleaning effect of a cleaning agent in combination with the solvent action of water and physical agitation of the lens (i.e., by means of rubbing) to achieve a degree of cleaning which is comparable to or better than prior processes which utilize surfactant-cleaners.  The cleaning agent is selected from polycarboxylates, polysulfonates and polyphosphates.  The preferred cleaning agent is citrate.  The process also offers greater convenience, relative to many prior systems for cleaning and disinfecting contact lenses, since the need to utilize additional products to clean the lenses is eliminated.

Abstract: A solder placement device (10) forms a selected length of a solder wire (14) to be used in mounting an optical fiber (20) to a substrate 116 so that the optical fiber (2)) and a laser diode (22) may be optically coupled together. The solder placement device (10) includes casing (16) that contains a plunger (24) arranged for reciprocal movement along an axis in the casing (16). A solder input tube (30) guides solder (14) from a supply spool (12) to a leaf spring retainer (42) inside the casing (16). The leaf spring retainer (42) is mounted to the plunger (24) and arranged to allow unidirectional movement of the solder wire (14) along the axis such that movement of the plunger (24) toward the output end of the apparatus (10) pulls the solder wire (14) along with the plunger (24). When the direction of the plunger (24) reverses, the leaf spring retainer (42) slides along the solder wire (14), and the apparatus (10) resets to pull in another segment of the solder wire (14). A cutting mechanism (86) is actuated by movement of the plunger (24) along the axis to cut off a piece (18) of solder of the selected length. An output tube (87) is mounted to the casing (16) adjacent the cutting mechanism (86). The output tube (87) is arranged to receive the cut off piece (18) of solder wire (14) so that compressed air blows it out through an end 110 of the output tube (87).

Title: Method of reducing wind gust loads acting on an aircraft
Inventor: KELM ROLAND
IPC: G05D1/02
Filed: 1999-04-30
Granted: 2008-06-17
Abstract: A method of reducing the bending moment effect of wind gust loads acting on the wing of an aircraft involves adjusting the aerodynamic configuration of the wing so as to alter the distribution of lift generated by the wing during phases of flight in which critical wind gusts are expected to occur. Particularly, during climb and descent phases of flight below cruise altitude, the lift generated by outboard portions of the wings is reduced while the lift generated by inboard portions of the wings is increased. Thereby, the 1g basis load acting on the outboard portions of the wings is reduced, and consequently the total load applied to the outboard portions of the wings, resulting from the 1g basis load plus the additional wind gust load, is correspondingly reduced. This leads to a reduction of the bending moments effective on the wings, and of any rolling moment effective on the aircraft. The required adjustment of the lift distribution is preferably achieved by deflecting the ailerons of both wings symmetrically upward and/or deflecting the flaps of both wings symmetrically downward during climb and descent. The adjustment of the wing configuration is carried out dependent only on flight parameters such as the altitude, speed and gross weight, and does not require rapid sensing of the occurrence of a wind gust and rapid actuation of control surfaces to try to instantaneously counteract a wind gust as it occurs.

Abstract: A bicycle saddle that is adapted to accommodate man's genitals has an elevated and slightly forwardly, downwardly inclined rear section. A lower horizontal narrower front section broadens from a forward end rearwardly to the rear section and joins the elevated rear section along a generally vertical plane forming an angle of 90° thus providing enough room to avoid contact of the genitals with the lower front section. The saddle is supported by a structure fixed to a seat post. As additional features, a central cut-out located in the lower section aims at decreasing the weight of the saddle, and a slight concave groove located on the rear section and oriented along the longitudinal axis of the saddle aims at receiving the coccyx of the user.
