  • Patent number: 9746013
    Abstract: A mounting clip and a mounting assembly include a mounting structure and the mounting clip. The mounting structure includes a mounting feature. The mounting clip includes a base, an inferior leg, and a catch. The base has a through hole therein. The inferior leg is disposed on an anterior side of the base. The catch is disposed on a posterior side of the base. The inferior leg and the catch are configured to engage the mounting structure when the mounting clip is assembled to the mounting structure, such that the mounting feature is accessible through the through hole when the mounting clip is assembled to the mounting structure.

  • Patent number: 9197283
    Abstract: A method and apparatus for sampling a high bandwidth analog signal includes: splitting the high bandwidth analog signal into N parallel channels; randomly demodulating each of the signals; sampling each demodulated signal using a sub-Nyquist sampling rate; combining each sampled signal into a sub-Nyquist signal; compressive sensing the combined sub-Nyquist signal to estimate missing samples of a full Nyquist rate uniform sample set X(n); convolving X(n) with N analysis filters, each analysis filter having a different coefficient; decimating output of each analysis filter using decimation ratios of M:1 to generate a sub-banded signal set Yi (n), i=1, . . . , N; processing the sub-banded signal set; up-sampling each processed sub-band signal by M; convolving each up-sampled sub-band signal with a corresponding synthesis filter; and combining two or more of the convolved signals to generate a non-uniform spectral partitioning of the high bandwidth analog signal.

  • Patent number: 8823573
    Abstract: System and method for converting a high bandwidth analog signal to a digital signal including: receiving the high bandwidth analog signal; splitting the high bandwidth analog signal to M parallel channels; delaying the split signal in each channel with N*T delays, respectively; sampling each M delayed signals by M relatively prime sampling rate, wherein the sampling rate for each M delayed signal is smaller than the Nyquist frequency of the high bandwidth analog signal; upsampling each M sampled signal, wherein the upsampling rate for each M sampled signal satisfies the Nyquist frequency of the high bandwidth analog signal; combining the M up sampled signals into a combined signal; and reconstructing the combined signal to generate a digital signal representing the high bandwidth analog signal.

  • Patent number: 7573026
    Abstract: A correction for pileup of measurements made by a nuclear detector is applied by selecting the energy of the first signal in a pileup, ignoring the remaining signals in the pileup, and correcting the count rate by a factor related to the total pulse widths within a unit time interval. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 6346094
    Abstract: A pen needle magazine dispenser for holding and dispensing a novel pen needle assembly. The pen needle magazine dispenser includes a number of threaded sleeves within cavities that interact with threads on each pen needle assembly to attach the pen needle to a special adapter on a conventional medication delivery pen. The magazine dispenser includes a sterility barrier and a cap to cover the pen needles.

  • Patent number: 5944700
    Abstract: A pen needle of the present invention includes an extender that is rotatably attached to a hub on the pen needle to set the pen needle to a desired injection length. The extender is rotated into multiple predefined positions using a shield that is removably mounted on the pen needle. Each predefined position for the extender corresponds to a predetermined injection length for the pen needle such that the extender covers a section of the pen needle not being used for the injection. After the shield has been used to rotate the extender into one of the predefined positions the shield is removed from the pen needle to expose the distal point of the pen needle so that the injection can be performed.

  • Patent number: 5941857
    Abstract: A disposable pen needle assembly is provided that includes a snap lock feature that provides a user with a simple method of detaching and attaching the pen needle to the medication delivery pen. In addition, the pen needle assembly includes a multi-use shield that initially shields the distal end of the pen needle prior to use and then both shields the proximal end of the needle and locks the used needle in its outer cover prior to disposal.

  • Patent number: 5931817
    Abstract: A pen needle having a cylindrical hub including a distal section that is received in a needle holder and a proximal section having threads that mate with a pair of lugs in an adaptor mounted on a medication delivery pen. The distal end of the pen needle includes a plurality of splines that mate with splines in the needle holder to prevent the pen needle from rotating within the needle holder and aid in threading the pen needle onto the adaptor. The pen needle is fully received in the needle holder to shield the proximal point of the pen needle and can only be removed from the needle holder by using the adaptor or a cartridge retainer having the proper pair of lugs thereon.

  • Patent number: 5873462
    Abstract: A pen needle dispenser having a cover rotatably mounted on a circular shaped container having a plurality of cavities, with each cavity dimensioned to receive a pen needle assembly with or without shields. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused shielded pen needle and thereby permits the pen needle to be mounted on a medication delivery pen. After use the used unshielded pen needle is returned to and locked in the cavity. Then, the cover is rotated until the slot is aligned with another cavity containing the next unused shielded pen needle to be used during the next injection. The pen needle dispenser prevents the cover from rotating the slot back to cavities containing used pen needles.

  • Patent number: 5829589
    Abstract: A pen needle magazine dispenser designed to be received and carried in a cap of a medication delivery pen. The dispenser having a cover rotatably mounted on a circular shaped container with a plurality of cavities, wherein each cavity is dimensioned to receive one pen needle. The pen needle being of a type that is forced fit into an adaptor on the pen using threads on the pen needle and corresponding threads in the cavity. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused pen needle and thereby permit the pen needle to be mounted on the pen. After use the used pen needle is returned to the cavity and the cover is rotated until the slot is aligned with another cavity containing the next unused pen needle to be used during the next injection.
