Title: Clock syncronous circuit
Inventor: YANG HYON-SOK
IPC: H03K5/00
Filed: 1993-02-24
Granted: 1995-07-11
Abstract: The precise clock synchronization circuit reduces the synchronization time error to a half clock period at asynchronous signal output mode. The circuit includes: (a) an edge detector which detects the edge of the clock signal; (b) the first synchronization circuit which delays the asynchronous data to synchronize with the edge detect signal; (c) the second synchronization circuit which shapes the first synchronization data to the second synchronization data according to the edge detect signal; (d) a transition detector which detects the transition state of the synchronization data using the second synchronization data signal and the first inverted synchronization data.

Title: Method and Structure for Multi-Cell Devices without Physical Isolation
Inventor: ERIC BROWN
Filed: 2015-09-15
Abstract: The present technology relates to multi-cell devices (200, 300) fabricated on a common substrate (116) that are more desirable than single cell devices (100), particularly in photovoltaic applications. Multi-cell devices (200, 300) operate with lower currents, higher output voltages, and lower internal power losses. Prior art multi-cell devices (100) use physical isolation (128, 138) to achieve electrical isolation between cells (126, 136, 146). In order to fabricate a multicell device (200) on a common substrate (116), the individual cells (225, 235, 245, 255, 322, 332, 342, 352) must be electrically isolated from one another. In the prior art, isolation generally required creating a physical dielectric barrier (128, 138) between the cells (126, 136, 146), which adds complexity and cost to the fabrication process. The disclosed technology achieves electrical isolation without physical isolation by proper orientation of interdigitated junctions such that the diffusion fields (390) pres

Title: Nano-Indentation Tests to Characterize Hydraulic Fractures
Inventor: Katherine Leigh HULL
Filed: 2020-08-30
Abstract: A rock sample is nano-indented from a surface of the rock sample to a specified depth less than a thickness of the rock sample. While nano-indenting, multiple depths from the surface to the specified depth and multiple loads applied to the sample are measured. From the multiple loads and the multiple depths, a change in load over a specified depth is determined, using which an energy associated with nano-indenting rock sample is determined. From a Scanning Electron Microscope (SEM) image of the nano-indented rock sample, an indentation volume is determined responsive to nano-indenting, and, using the volume, an energy density is determined. It is determined that the energy density associated with the rock sample is substantially equal to energy density of a portion of a subterranean zone in a hydrocarbon reservoir. In response, the physical properties of the rock sample are assigned to the portion of the subterranean zone. Fig 1A.

Abstract: ITCH RELIEVING DEVICE 
ABSTRACT 
An itch relieving device is disclosed, including a shell (100), a heating element (200), 
a first touch sensing module (300), a control module (400) and a gear input module (500).  
The first touch sensing module (300) is configured for touching a human body to generate a 
human body sensing signal, the control module (400) is electrically connected with the 
heating element (200) to control the heating element (200) to be switched on or off according 
to the human body sensing signal, the gear input module (500) is configured for acquiring a 
control action to generate a pulse signal, the control module (400) is provided with a storage 
unit (410), the control module (400) is electrically connected with the gear input module 
(500) to change a heating gear according to the pulse signal, the control module (400) records 
the current heating gear through the storage unit (410), and the control module (400) controls 
a heating power of the heating element (200) according to the current heating gear. The 
disclosure relates to the technical field of appliances, and more particularly, to an itch 
relieving device.
