  • Patent number: 11938250
    Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological molecule.

  • Publication number: 20220304424
    Abstract: A shoelace locking apparatus includes an elongated body having an exterior and a channel. The channel has a diameter sized to receive a shoelace in friction fit relation. A tab is secured to and projects outwardly from the exterior sidewall of the body. The tab has an aperture. The aperture has a diameter sized to receive a shoelace in friction fit relation and is oriented crosswise to the channel. A force in a first direction that would otherwise be sufficient to dislodge the shoelace from the aperture is resisted with the shoelace held fast in the channel. A force in a second direction that would otherwise be sufficient to dislodge the shoelace from the channel is resisted with the shoelace held fast in the aperture.

  • Publication number: 20140002343
    Abstract: A system and method tracks a user's eye for a data trigger arrangement. The method includes obtaining first image data within a first vision field of a first data capturing sensor. The method includes determining a first area viewed by a user's eye as a function of the first image data. The method includes obtaining second image data within a second vision field of a second sensor. The method includes determining a second area captured within the second field of vision as a function of the second image data. The method includes determining disposition data of the first area within the second area. When a trigger command is captured, the method includes data capturing a machine readable representation of data (MRRoD) using the second sensor as a function of the disposition data.

  • Publication number: 20080141052
    Abstract: A device having a plurality of contact points providing connectivity between the device and a further device, a detection point providing connectivity between the device and the further device, wherein, as the further device is disconnected from the device, the detection point is disconnected prior to at least a portion of the plurality of contact points and a processor detecting the disconnection of the detection point and performing an action related to the detection of the disconnection.

  • Publication number: 20070118544
    Abstract: Described is a computing device comprising a first decoding module and a second decoding module. The first decoding module decodes information from a standard format media file. The second decoding module decodes additional data embedded in the standard format media file. The additional data is compatible with the standard format media file. The additional data directs operation of the computing device for the information decoded using the first decoding module.

  • Publication number: 20070019802
    Abstract: Systems and methods of synchronizing an input signal and an output signal via employing a sampling component that samples a speaker output and a microphone input during a full duplex communication, at a same clock frequency and same exact time to supply time synchronized sample signal(s). A software acoustic echo canceller (AEC) can then provide for production of a reconditioned microphone signal, wherein the speaker signal is absent therefrom. The time synchronized samples can be processed by the software AEC, in general without real time constraints that can be imposed by the operating system (OS).

  • Publication number: 20060092290
    Abstract: Described are a device and a method for acquiring data using a camera port of a processor. The device includes a processing unit; a memory arrangement storing a set of instructions; and a camera port. The camera port is configured to receive first data in a first format from a camera-type arrangement. The camera port receives from a non-camera type data acquisition device second data in a second format and the processing unit converts the second data into further second data stored in the first format using the set of the instructions.

  • Patent number: 6799455
    Abstract: A tire pressure monitor continuously indicating to a vehicle operator whether or not each tire on the vehicle, including a spare if present, is adequately inflated for safe “over-the-road” operation. The monitor includes an indicator associated with each tire to indicate when the air pressure in any individual tire on the vehicle is not inflated to a pressure adequate for safe operation. The monitor also includes a battery operated pressure sensitive radio frequency transmitter mounted on the outer end of a conventional tire valve stem and includes an antenna extending into each tire for transmitting a signal to an indicator assigned to each tire without interference from metal wheel components. The indicators are mounted on the instrument panel or dashboard of the vehicle. The signal transmitted from the transmitter on each tire valve actuates only the indicator associated with and receiving a signal from only the transmitter assigned to each tire.
