An electromechanical dynamic force profile articulating mechanism for recovering or emulating true parallel plate capacitor actuation behaviors from deformable membranes used in MEMS systems. The curved deformation of flexible membranes causes their MEMS behavior to deviate from known interactions between rigid plates that maintain geometric parallelism during ponderomotive actuation. The present invention teaches three methods for reacquiring parallel plate behavior: superaddition or in situ integration of a rigid region within or upon the deformable MEMS membrane; creation of isodyne regions to secure parallelism by altering the force profile upon the membrane by introducing tuned and shaped voids within the conductive region associated with the membrane; and a hybrid composite approach wherein the conductive region is deposited after deposition of a raised rigid zone, thereby emulating isodyne behavior due to the increased inter-conductor distance in the vicinity of the rigid zone, in conjunction with rigidity benefits stemming directly from said zone.

A projected force-based input device comprising a projected or elevated contacting element configured to receive an applied force, a sensing element located in a different plane with respect to the contacting element, and a sensing portion operably supported to displace in response to the applied force. The sensing element further comprises a plurality of sensors operable to output sensor data corresponding to the applied force, wherein the sensor data facilitates the determination of a location of the applied force occurring about the contacting element, as well as the profile of the applied force over time (e.g., waveform), otherwise known as the force profile. One or more transfer elements may also be present, which function to relate the contacting element to the sensing portion of the sensing element so as to transfer substantially all of the applied force from the contacting element to the sensing element. Adequate rigidity between the elevated contacting element, and transfer elements, and the sensing element is intended to be maintained in order to prevent interference with any mounting or other structures or objects, and to permit the input device to operate properly.

A system and method are provided for real-time measurement of tool forces. A relationship between a sensor characteristic and tool forces is determined by first directly measuring tool forces for a standard tool, work piece, and part program in a central facility. A force profile indicative of the tool forces and the standard tool, work piece, and part program are provided to a user at a user facility. The sensor characteristic for a CNC machine at the user facility is then measured for the standard tool, work piece, and part program. Based on the force profile determined at the central facility, the relationship between the sensor characteristic and tool forces is determined. Thereafter, the sensor characteristic of the CNC machine is measured for a work piece, part program and desired tool and converted to tool forces using the relationship between the sensor characteristic and tool forces. The resulting tool forces may be combined with a process model to obtain process model parameters or cutting energies for the work piece and the desired tool. In cases where the sensor is not conveniently attached to the work piece or when the part program is not sufficiently robust in cutting conditions to accurately determine the process model parameters, the work piece and part program are replaced by a sacrificial work piece and sacrificial part program. The sacrificial work piece and sacrificial part program are selected to both accommodate the sensors and to provide sufficient robustness in cutting conditions to accurately determine the process model parameters for the sacrificial work piece. The process model parameters for the desired work piece are obtained from the process model parameters by, first, obtaining the averaged tangential tool forces for the desired work piece and for the sacrificial work piece by measuring the spindle motor power and applying the relationship between spindle motor power and tangential tool forces for each work piece, second, obtaining a ratio of the averaged tangential tool forces for the desired work piece and the sacrificial work piece and, third, applying this ratio to the process model parameters for the sacrificial work piece to obtain predicted values for the tool forces and the process model parameters for the desired tool and desired work piece.

A pinch detection system and method controls the speed of a motor moving an object by first calculating the actual motor force and then comparing the actual motor force with a reference force value in a reference field. A pinch condition is indicated if the difference between the actual force and the reference force exceeds a selected pinch threshold. The difference is also used to update the reference field, the pinch threshold and the desired speed of the motor so that the reference field will eventually reflect the actual force profile of the object. The updated pinch threshold is also used to control the motor speed so that the pinching force remains constant regardless of the pinch threshold value.

The present invention provides a device for determining the dynamics of a tool sited in a CNC machine, as encapsulated by the Frequency Response Function. The device uses an actively controlled electromagnet to excite forces on the tool. The force is excited in a non-contact manner, allowing the force to be applied to both a stationary and a rotating tool. The displacement is measured by standard means, such as accelerometers, optical displacement or capacitance sensors. The ratio of the force and the displacement in the frequency domain is the Frequency Response Function. The force may be applied as a pure sine wave, providing the Frequency Response Function at the frequency of the sine wave. Varying the frequency of the sine wave provides the Frequency Response Function over the range of frequencies of interest. The control of the force profile is handled entirely by the automated controls and requires no special skills, training or manual interaction by the user. No separate force sensor is required, since the electromagnetic force on the tool may be accurately determined from the design of the electromagnet and the tool position, geometry and material.

The system may also include a discontinuous force profile for a restoring force mechanism that provides tactile feedback to the pilots simulating resistance provided by control surfaces of the aircraft. The system may also include an autopilot lockout mechanism that increases the force profile experienced by the pilots when autopilot mode is entered.

In order to injection mold parts at a constant flow front velocity in a mold cavity of an injection molding system, particularly where the mold cavity has a varying thickness along its length, mold modeling software is used to calculate the cross-sectional area as a function of the distance from the gate, percentage of fill, or length of the mold cavity. Based on that cross-sectional area, the mold modeling software determines an appropriate recommended ram force profile and / or melt pressure profile that would result in filling the mold cavity at a constant flow rate. An injection molding system is then operated according to the recommended ram force profile and / or melt pressure profile.

A silicone coating process that improves the durability of silicone coatings on the surfaces of surgical needles and other medical devices. The silicone coated surgical needles or medical devices produced by this process have both superior lubricity and durability for ease of repeated and successive passes through tissue. The coating compositions used in the novel process contain an excess amount of polymethylhydrosiloxane cross-linker. After curing, the process utilizes gamma radiation to treat the lubricious coatings. The coatings have improved durability and performance. The penetration performance of needles coated by this novel method remains constant and flat over at least one hundred repeat passes through tissue or tissue simulation media. This provides a consistent or flat tactile response from the needles to the hand of the surgeon during a lengthy closure process, rather than an unpredictably increasing force profile. The process is also advantageous to coat reusable instruments, robotic instruments, and instruments used in minimally invasive procedures.
