Patent number: 11897678Abstract: The paper recyclable heat sealable bag includes a heat sealable water soluble inner layer coating and an article of paper. The heat sealable coating is applied to the article of paper by a printing press. As the printing press applies the heat sealable coating to the article of paper, the paper recyclable heat sealable bag may be wound into a master roll with a plurality of paper recyclable heat sealable bags. The master roll is fed into an automatic packaging system which fills the bags with a product from at least one of a top edge and a side edge of the paper recyclable heat sealable bags. The paper recyclable heat sealable bag has certain perforations to remove the paper recyclable heat sealable bag more easily from the master roll and sealed with a heat sealer.Type: GrantFiled: October 13, 2021Date of Patent: February 13, 2024Assignee: PACKAGING AIDS CORPORATIONInventor: Gregory Berguig

Publication number: 20120140937Abstract: A method for adjusting a hearing instrument to reduce feedback by placing a hearing instrument having an adjustable frequency response in a wearer's ear, providing a probe microphone for measuring the sound pressure level inside the ear and a reference microphone for measuring the sound pressure level outside the ear, exposing the ear to a stimulus and a dynamic event, determining the gain as a function of frequency from the difference in sound pressure level measured by the probe microphone and the reference microphone, identifying a feedback peak where the frequency is in the center of a range of frequencies and corresponds to the maximum gain in that range of frequencies and adjusting the hearing instrument to reduce the gain at a frequency corresponding to the frequency of the feedback peak.Type: ApplicationFiled: February 10, 2012Publication date: June 7, 2012Applicant: Magnatone Hearing Aid CorporationInventors: Michael L.

Patent number: 7436378Abstract: An LED terminal monitoring circuit detects an LED at the lowest potential among a plurality of parallel-connected LEDs. An analog signal selecting circuit gives a signal indicating the voltage of the detected LED to a boosting circuit. The boosting circuit performs a boosting operation on the basis of the condition of the detected LED at the lowest voltage and, consequently, a voltage sufficient for driving the LEDs in a current-control mode can be applied to all the LEDs. Signal lines not connected to LEDs are excluded from objects of a LED-switching control operation.Type: GrantFiled: October 2, 2004Date of Patent: October 14, 2008Assignees: AL-AID Corporation, Sharp Kabushiki KaishaInventors: Satoru Ito, Seijun Nishimura, Toshiya Fujiyama

Publication number: 20070188426Abstract: Disclosed is an LED driver circuit that can suitably detect a minimum voltage and can be produced at low cost. A selector circuit is comprised of a comparator C, an inverter I and analogue switches. A minimum voltage selecting circuit can be constructed by causing the selector circuit and a circuit constructed in the same manner as the selector circuit is done, to be combined with each other. Therefore, the minimum voltage selecting circuit can be comprised of active devices that comprise only p-MOSFETs and n-MOSFETs. Moreover, as a semiconductor process structure, there may be employed a so-called single WELL structure in which a WELL is not formed in another WELL. The LED driver circuit is formed at low cost.Type: ApplicationFiled: February 10, 2006Publication date: August 16, 2007Applicant: AL-AID CorporationInventors: Satoru Ito, Seijun Nishimura

Patent number: 6103800Abstract: An acrylic liquid monomer and powdered polymer that, when mixed, cures with workable characteristics over its entire polymerizing phase. As the mixtures cures, its consistency continuously transforms from a castable material to a spreadable, glue-like liquid to a paste to a putty to a reformable clay and finally to a hard plastic. The invention's continuous and non-rubbery curing properties make it easy to work and give it a broad spectrum of uses. The invention may be supplied in the form of a kit.Type: GrantFiled: May 21, 1998Date of Patent: August 15, 2000Assignee: Plast-Aid CorporationInventors: Dale A. Peterson, Randall M. Amen
