A three position, selectively openable twist lid for a drinking vessel has separate drinking and venting apertures. The lid has two parts—a base member and a cap member. The base and cap members can be relatively rotated from a first, closed position to a second, open position and to a third, disengaged position in which the cap and base members may be separated for cleaning.

A stake for insertion in soil to support an item such as a plant. The stake includes primary and secondary telescoping shafts and a foot adjustably secured to the primary shaft. The primary shaft has an upper end and a lower end. The lower end is configured for insertion into the soil at a first location. The foot has a supporting protrusion for insertion into the soil at a second location removed from the first location. Retractable ties are disposed within the secondary shaft and may be extended to support a plant. An adjustable collar may provide an anchor point for additional support.

A direction finding antenna system for determining the relative bearing of a second aircraft from a first aircraft in conjunction with Distance Measuring Equipment (DME). The system includes a first antenna and a second antenna located on a top surface of the first aircraft, spaced apart along a first axis, as well as a third antenna and a fourth antenna located on a bottom surface of the first aircraft, spaced apart along a second axis orthogonal to the first axis. The system further includes a transmitting, receiving, and processing system coupled to the first, second, third, and fourth antennas, wherein the transmitting, receiving, and processing system is configured to transmit DME interrogations, receive DME replies, and process the DME replies to determine the relative bearing of the second aircraft from the first aircraft.
摘要:
A method for a geometry of a lateral comb drive for an in-plane, electrostatic force feedback, closed-loop, micromachined accelerometer or closed-loop Coriolis rate gyroscope device, or closed-loop capacitive pressure or force measuring device. When vibration is applied to the device, the error in the time-average output, which is vibration rectification error, due to this input vibration is minimized or eliminated. The geometry resulting from practice of the present invention is space-efficient because drive force is maximized while vibration rectification is minimized or eliminated.

A preloaded differential includes may take the form of a hold-out ring type locking differential having a preloaded thrust assembly that may be insertable in the differential as a one-piece unit. The preloaded thrust assembly includes a pair of thrust members each having complimentarily shaped protruding and recessed portions that interlock after assembly to prevent rotation of the thrust members relative to one another. Further, one or more conical, disc-shaped springs may be located between the thrust members to bias the thrust members directly against side gears positioned within the differential to reduce or prevent radial movement of the side gears. In one embodiment, the thrust members include a friction and thrust contact surface that directly contacts the side gears and the springs are located within a region formed by the interlocking features of the thrust members.

Methods and systems for analyzing vibrations of a vehicle acting on a person. The person uses a sprung vehicle seat. A detection unit detects acceleration values fitted to the vehicle seat in the x-, y- and z-axes at preset intervals of time. An increase over time of the acceleration values cumulated with one another is determined and a time calculated from this when a pre-determinable permitted maximum of the cumulated acceleration values will foreseeably be reached.

A four-way, field-reversible self-latching cabinet lock includes a cylinder and plug assembly shell that is rotatable with respect to a bolt housing cover for the lock. A locking device is provided to fix the cylinder and plug assembly shell in one of four orthogonal positions with respect to the bolt housing cover. The bolt housing cover is receivable by a bolt housing and conventional self-latching latch bolt. In this manner, pins in the cylinder and plug assembly may be retained in a desirable vertical position while a throw of the bolt can be adjusted to vertical, inverted, left-hand, and right-hand positions in the field without special tools or additional parts.
