  • Patent number: 11344419
    Abstract: A femoral component kit includes a piston. The piston includes a notch formed in a bottom surface. The kit includes a femoral component mold having a mold body with a first sidewall, a second sidewall, and a bottom. The sidewalls and bottom define a recess for receiving an antibiotic-impregnated material. The recess includes depressed sections that are spaced apart by an inner section. The outer sections are transverse to a longitudinal axis of the mold. The inner section includes a keel that extends upward and has a height that sets a size of a femoral component produced using the mold. The keel is aligned with the notch when the piston is inserted within the mold. The notch and the keel may include one or more calibration markings that indicate increments of adjustments to the size of the femoral component and resulting flexion and extension gaps and joint space position.

  • Patent number: 6707093
    Abstract: A touch-sensitive semiconductor chip having a physical interface to the environment, where the surface of the physical interface is coated with a fluorocarbon polymer. The polymer is highly scratch resistant and has a characteristic low dielectric constant for providing a low attenuation to electric fields. The polymer can be used instead of conventional passivation layers, thereby allowing a thin, low dielectric constant layer between the object touching the physical interface, and the capacitive sensing circuits underlying the polymer.

  • Patent number: 6195002
    Abstract: Alarms for testing sensors, particularly those used in fire-suppression systems, are described. In one aspect of the invention, the alarm includes an audio and/or a visual indicator operably coupled to the housing of a sensor. The audio indicator may be a speaker that beeps when the sensor is activated. The visual indicator may be one or more LEDs that are illuminated when the sensor is activated. The alarm also can be used to determine whether power and ground conductors extending to the sensor are properly connected. Additionally the alarm can be used to determine whether one or more conductors extending from the sensor to the control panel are properly connected. Certain applications of the invention are intended primarily for use with existing fire-suppression-systems. The invention also can be employed in new fire-suppression system installations using a dry-contact circuit embodiment of the invention (FIG. 5).

  • Patent number: 5748973
    Abstract: An automated, user-interactive procedure is used to obtain the right statements for computer software from the user in a way in which the statements elicited from the user are free from errors due to ambiguity, conflict, redundancy, inconsistency, and the like without compromise of user intent. The advanced integrated statements engineering system (AIRES) is an integrated environment, supporting and spanning the statements engineering life cycle. Each activity in the statements engineering life cycle is supported by a set of automated CASE tools, which taken together, comprise a suite of CASE tools in the AIRES environment. A primary feature of the assessment framework is a classification ectype (CE), which is a combination of operator controlled rules and tables to represent a category within a classification structure. CE-based statements assessment (CEBRA) provides automated support techniques to "recognize" and thus categorize English text.

  • Patent number: 5646581
    Abstract: A termination device including a package having a first plurality of pins and a plurality of resistors disposed in the package is described. Each resistor has a pair of termini with one of the termini of each resistor connected to a corresponding one of the first plurality of pins and the other termini connected to a common conductor. The device also includes a reference conductor connected to a mid-portion of the common conductor and to a pin of the package. An alternate embodiment of the termination device includes two reference conductors connected to respective end portions of the common conductor and to pins of the package.

  • Patent number: 5016204
    Abstract: An expert system for performing a redesign operation in connection with an original design. A working memory includes a plurality of blackboards each for storing a design representation and desired operational characteristics. A simulation component comprises a plurality of simulators each for generating simulated operational characteristics in connection with a design representation on one of said blackboards. A diagnostic component identifies operational discrepancies between the simulated operational characteristics and the desired operational characteristics and the causes of the operational characteristics. A redesign component generates a redesign of the design representations on the blackboards in response to the original design and the identified dicrepancies and discrepancy causes.

  • Patent number: 4751600
    Abstract: Apparatus for use in cleaning a tape head comprises a cartridge in which there is a frame carrying tape head cleaner in the form of a spindle carrying a foam sponge cleaning roller. For reciprocating the tape head cleaner against a tape head in use of the apparatus, the frame is movable by any one of first, second and third rotatable shafts in the cartridge. The shafts are coupled with the frame and rotation of any one of them about its longitudinal axis causes movement of the frame.
