Publication number: 20240398290Abstract: Methods, systems, and devices for continuous glucose monitoring. More particularly, the methods, systems, and devices describe a working electrode with a GOx sensor and a background electrode in which the background electrode has no GOx sensor. The system may then compare the first signal and the second signal to detect ingestion of a medication by the user. The system may generate a sensor glucose value based on the comparison.Type: ApplicationFiled: August 13, 2024Publication date: December 5, 2024Inventors: Soroush Hossein Yazdi, Melissa Tsang, Ellis Garai, Sadaf S. Seleh, Steven Lai, Luis A. Torres, Bradley Petkus, Xin Heng, Zhenzhong Sun, Akhil Srinivasan, Tyler R. Wong

Patent number: 8656833Abstract: A leveling machine for rolled-up tablets has a base, a mounting frame and a wheel-leveling device. The base has two sideboards faced each other and each sideboard has a spindle hole. The mounting frame is rotatably mounted in the base between the sideboards and has a spindle, an adjusting motor, two mounting boards and a bottom cylinder. The spindle is rotatably mounted in the spindle holes of the sideboards. The adjusting motor is mounted securely on the corresponding sideboard to drive the spindle. The mounting boards are respectively, obliquely and securely mounted around the spindle near the sideboards. The bottom cylinder is rotatably mounted around the spindle between the mounting boards. The wheel-leveling device is connected to the mounting frame and has two top cylinder mounts, a cylinder, a top cylinder, two pushing mounts and two telescopic drivers.Type: GrantFiled: September 22, 2011Date of Patent: February 25, 2014Inventor: Steven Lai

Publication number: 20130072366Abstract: A coil-tube chunk for a roll feeder has at least one colleting device. Each of the at least one colleting device has a base and a chunk. The base has a mounting stand, a sharp-tooth mount and multiple screwing rods. The mounting stand is formed on and protrudes from the base. The sharp-tooth mount is formed on the base around the mounting stand. The screwing rods are respectively and securely mounted on the sharp-tooth mount. The chunk is mounted securely on the base and has a guiding face, multiple grooves and multiple engaging teeth. The guiding face is aslantly formed on an external surface of the chunk. The grooves are formed in the external surface and the guiding frace of the chunk at intervals. The engaging teeth are formed on the external surface and the guiding face of the chunk between the grooves.Type: ApplicationFiled: September 18, 2011Publication date: March 21, 2013Inventor: Steven Lai

Patent number: 7270891Abstract: A passive thermal control blanket and a method for its manufacture, the blanket including a plastic substrate on which is deposited a film that is a homogeneous mixture of silicon and germanium, thereby combining the excellent reflective and electrostatic discharge properties of germanium with the superior adhesion and corrosion resistance properties of silicon. The uniform mixture is preferably obtained by sputtering the two materials simultaneously onto the substrate, using either separate targets, a single mosaic target, or a single composite target.Type: GrantFiled: November 17, 2004Date of Patent: September 18, 2007Assignee: Northrop Grumman CorporationInventors: James A. Roth, James T. Hall, Dennis G. Neal, Craig R. Wilkinson, Steven Lai, Mark W. Johnson

Patent number: 6333959Abstract: A simplified bi-directional shift register and a single-latch circuit for implementing the bi-directional shift register thereof which obviates the use of a conventional dual-latch (i.e., master/slave) configuration in the bi-directional shift register design is described. The single-latch circuit includes an input circuit portion and a latching circuit portion. The input circuit portion receives input signals including the output data from previous and next single-latch circuits in the shift register and right shift and left shift control signals. Dependent on the input signals, the input circuit portion drives an input node coupled to the latching circuit portion with a data value to be shifted which corresponds to data from one of the previous and next single-latch circuits.Type: GrantFiled: April 25, 2000Date of Patent: December 25, 2001Assignee: Winbond Electronics CorporationInventors: Steven Lai, Je-Hurn Shieh

Patent number: 6323705Abstract: A double data rate (DDR) synchronous dynamic RAM (SDRAM) includes delay lock loop circuitry which is designed so as to significantly reduce the locking period associated with achieving the lock state of the delay lock loop. The delay lock loop circuit includes a first adjustable delay unit circuit for delaying the external clock so as to provide the DDR operation and includes a feedback loop having a shift register controlled by a phase detector which is used to set an optimum delay value. The delay value is then used to control the first delay unit circuit and determine the amount of delay time it provides.Type: GrantFiled: April 25, 2000Date of Patent: November 27, 2001Assignee: Winbond Electronics CorporationInventors: Je-Hurn Shieh, Steven Lai
