Vehicle suspension spring system

A vehicle suspension spring system for a vehicle wheel station includes a hydraulic cylinder or strut having a piston which divides the cylinder volume into a main oil volume and an annular oil volume. The main oil volume communicates via a first oil passage with a first accumulator having a main gas volume. The annular oil volume communicates via a second oil passage with a second accumulator having an auxiliary gas volume. The oil in each accumulator is separated from the gas by a separator piston or diaphragm. A third oil passage with an isolating valve interconnects said first and second oil passages. Operation of the isolating valve is regulated by a controller. At least one sensor for sensing a parameter associated with vehicle attitude is connected to the controller. The controller is operable for switching the isolating valve between open and closed positions for altering spring stiffness of the strut in response to said sensed vehicle attitude parameter when the vehicle is in motion.

Snake plunger

This invention relates to a drain plunger that snakes clogged drains at the same time that the drains are being plunged. The “snake plunger” includes a pleated bellows forming a head section which is removably coupled to a handle. Further, in one embodiment, the head and handle sections are jointly configured to release air from within the bellows while the plunger is being inserted into a basin filled with wastewater, thereby reducing or eliminating potential spillover. Further, a flexible elongated snake disposed within the interior of the bellows enters the drain as the plunger bellows is compressed. The snake is capable of dislodging and breaking up obstructions within a drain. Further, the snake may also have a hook at its lower end that is capable of snaring items causing obstructions within the drain. These features combine to create a plunger that provides a superior ability to effectively clear clogged drains.

Dental attachment assembly cap and method of use

A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

Shock-limiting interface, compact (SLIC)

A passive / reactive device protests a Payload from injury or damage due to the shock caused by impact or explosion. When the vehicle or structure mounting the Payload receives a shock pulse, the invention limits the acceleration transmitted from the vehicle or structure to the Payload to an acceptably low, user-adjustable level which is substantially constant or is some other user-adjustable force-displacement function. The invention is capable of doing so even when the peak magnitude of the imposed shock is on the order of thousands of G's, with a rise time to peak on the order of microseconds. The invention can be embodied to operate passively, without any external source of power, sensor system, or CPU, although they can be added to improve certain usability features. The invention also absorbs or dissipates the shock energy in substantially the minimum distance possible without exceeding the user-defined acceleration limit on the Payload. The invention can also react when a shock-producing impact is imminent by repositioning the Payload away from the impact site. The Payload can be a person or persons, or shock-vulnerable equipment. The shock can be created in a number of ways, including an explosion, an impact or collision, the slamming on high-performance boats and some off-road vehicles, earthquake, or even intentional shocks on an amusement thrill ride. The ability of the invention to protect against shock is limited only by its ability to absorb or dissipate the energy of the shock pulse on the Payload. The device can be implemented to protect against shock from any arbitrary direction. The name Shock-Limiting Interface, Compact (SLIC) is coined for this invention.

Electrostatic actuator

An electrostatic actuator includes a substrate upon which substantially U-shaped support beams are arranged such that a movable element is displaceable in the Y-axis direction. Then, the movable element is displaced from an initial position to a switching position by an electrostatic force between electrodes. When the movable element is at the initial position, the support beams are configured such that the arm portions of the support beams are not parallel to each other and, when the movable element is displaced by a large amount to the vicinity of the switching position, the arm portions are extended in the X-axis direction so as to be substantially parallel to each other. Thus, since the spring constant in the X-axis direction of the support beams is increased, transverse locational deviations when the movable element is displaced and short-circuiting by the deviations are prevented and, as a result, the movable element can be stably displaced by a large amount.

Method of tone reproduction with halftone dots, apparatus for outputting halftone plate, halftone plate, and printed material

InactiveUS6970273B1Eliminating tone jumpSmoother tone reproductionScreening processesVisual presentationTone reproductionComputer science
Tone jumps are eliminated in all areas ranging from a highlight area through an intermediate tone area to a shadow area for thereby achieving a smoother tone reproduction. Halftone dots are grown in a circular shape from a halftone percentage of 0% to a first highlight percentage. Halftone dots are grown while changing from the circular shape to a square shape from the first highlight percentage to a second highlight percentage greater than the first highlight percentage. Halftone dots are grown in a square shape from the second highlight percentage to a second shadow percentage. Halftone dots are grown while changing from the square shape to a circular shape from the second shadow percentage to a first shadow percentage greater than the second shadow percentage. Halftone dots are grown in a circular shape from the first shadow percentage to a percentage of 100%. The dots stick well to the print sheet in the highlight area and clearly define inter-dot spaces in the shadow area, and no tone jumps occur in the vicinity of the halftone percentages of 50% and 78.5%.
