  • Low-voltage controller with dimming function and method
    Patent number: 10575387
    Abstract: A low-voltage controller (LVC) is configured to utilize a low-voltage signal to operate a high-voltage load, such as a lamp. The LVC is configured to receive a low-voltage step signal at a switch input. The LVC has a line input for connection to a source of power at a line voltage and a load output for connection to a first load, and a dimmer for setting an intensity of the first load. Subsequent step signals alter the intensity of the load. A method for low-voltage control of the load is provided. A method includes the steps of receiving a first switch signal at a switch input of an LVC; setting a lamp to a first intensity; receiving a second switch signal at the switch input; and setting the lamp to a second intensity.

  • Convertible plungers, film coated plungers and related syringe assemblies
    Patent number: 10561795
    Abstract: A convertible plunger is provided comprising an internal portion and a generally cylindrical exterior surface. At least a portion of the exterior surface is maintained in an initial expanded state by a property of the internal portion. The expanded state is reducible to a constricted state by an operation that is applied to the internal portion of the plunger to alter the property. A film coating may also be applied to a sidewall of the sleeve to reduce a sliding friction between the sleeve and barrel. A film coating may also be applied to a nose cone of the plunger to provide a barrier between the plunger and product in the barrel.

  • Trilayer coated blood collection tube with low oxygen transmission rate
    Patent number: 10537494
    Abstract: An article is described including an article surface and a coating set comprising an optional tie coating or layer, a barrier coating or layer, and a pH protective layer. The respective coatings or layers can be applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. Examples of such an article are a thermoplastic syringe, vial, or blood collection tube with a coated interior portion containing a pharmaceutical preparation or other fluid with a pH of 4 to 8, alternatively 5 to 9. The barrier coating or layer prevents oxygen from penetrating into the thermoplastic syringe, vial, or blood collection tube. The tie coating or layer, if present, and the pH protective coating or layer protect the barrier layer from the contents of the syringe, vial, or blood collection tube.

  • Presentation of biopsy sample by biopsy device
    Patent number: 10517577
    Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively align each of the chambers with the cutter lumen. A controller in communication with the rotation mechanism is configured to rotate the manifold to a presentation position to present a collected tissue sample within a chamber to a user (e.g., at an angular position approximately 90 degrees from the cutter lumen). The controller is further configured to rotate the manifold align the next, empty chamber with the cutter lumen in response to a user input instructing the biopsy device to obtain another tissue sample.

  • Detection of reversible nerve injury
    Patent number: 10517493
    Abstract: A system for monitoring relative nerve health and the presence of neuropraxia is described. The system utilizes the integration of a waveform function of an elicited or monitored nerve response to provide an indication of the strength of a detected signal from a nerve and thus the relative health and integrity of the nerve. In some embodiments motor nerve stimulation innervates muscle and an EMG waveform is obtained in response thereto. The integration under the waveform is expressed and an indexed value indicating a percentage of a certain threshold value. Methods set forth provide a more reliable status of a nerve in real-time and allow action to be taken to reduce neuropraxia or prevent permanent nerve damage.

  • Method and Apparatus to Provide Safety Checks for Neural Stimulation
    Publication number: 20190366089
    Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.
