摘要:
A protection element and a protection device for a camera drone are disclosed herein. The protection element is installed between a landing gear and a propeller of the camera drone and comprises a fixing bracket joined to a brace of the propeller and positioned between the landing gear and the propeller; a protection ring positioned around the exterior of the fixing bracket; and at least one buffer stick joined to the fixing bracket and the protection ring. The protection elements may also be installed on a camera drone having more than two propellers to function as a protection device for the camera drone. While an unpracticed user operates a camera drone, the present invention can protect the propellers of the camera drone flying in a narrow space from directly bumping into a foreign object preventing the camera drone from crashing.

An improvement reducing or eliminating noise between drivers connected in common on a single chip. A DC power source (VDD1) providing a common signal to multiple PCML drivers and inductance introduced between a common DC power source and each of the multiple PCML drivers tied in common to the DC power source. The introduced inductance between VDD1 and each of the multiple PCML drivers reduces or eliminates AC noise from flowing between drivers and allows DC signaling to pass to all drivers commonly connected to VDD1.

An implementation of NMF functionality integrated into a relational database management system provides the capability to apply NMF to relational datasets and to sparse datasets. A database management system comprises a multi-dimensional data table operable to store data and a processing unit operable to perform non-negative matrix factorization on data stored in the multi-dimensional data table and to generate a plurality of data tables, each data table being smaller than the multi-dimensional data table and having reduced dimensionality relative to the multi-dimensional data table. The multi-dimensional data table may be a relational data table.

The invention is directed toward a lapping apparatus and method for accurately obtaining the height of a magnetoresistive (MR) element of a magnetic head during a lapping process. The apparatus includes a source for inducing a magnetic excitation field, and a current source for applying a sense current to a prepatterned photolithographically formed MR element. A sensor monitors the resistance of the MR element in response to variations in the magnetic excitation field, and controls the lapping process in response to the monitored resistance of the MR element. In one embodiment, the MR element includes a GMR formed of a stack of parallel MR layers and operates either in a CPP (Current-Perpendicular-to-the Plane) mode or in a CIP (Current-In-the Plane) mode. In a particular embodiment, the magnetic excitation field is generated by a conductor formed on the magnetic head.

An automatic record detection device and method for stop arm violation event, comprising: a plurality of image fetching units, to fetch external video signals; at least an analog-to-digital converter, to process said external video signal into digital data; a processor unit, to detect dynamic images of said digital data based on a set sensitivity value, when said set sensitivity value of said dynamic image of a violating vehicle fulfills an image block number, it determines said dynamic image to trigger a violation event, then generates said digital data based on said external video signal. As such, a user can search said dynamic images of said digital data by examining said triggered violation event, to find out license plate number of a violating vehicle, and sends it to an agency concerned for prosecution, thus saving enormous time and manpower in viewing and searching through said digital data.

The improved PCML communications driver corrects current loss and reduced voltage swing when driving an LVDS receiver load by reducing the value of the Rt1 resistors. By changing the value of the two Rt1 resistors from Rt1 to Rt1/2 (or lower), the full bias current can be restored and voltage swing is substantially improved. By making Rt1 a programmable resistor so Rt=Rt1/2 for DC bias calculation, Q2 bias current is increased back to IB, instead of IB/2.
摘要:
A system, apparatus and method for testing and measuring high frequency signals on a trace is described. In one embodiment of the invention, a footprint is manufactured on a trace to allow the testing of a signal while reducing the amount of distortion caused by prior art structures and methods. The footprint is designed to reduce stub effects and capacitance on a signal being communicated on the trace.

The present invention discloses a device integrating a rearview mirror and a driving recorder screen, which comprises a rearview mirror baseplate having at one rotary shaft on one lateral thereof; a mirror installed in the rearview mirror baseplate; and a driving recorder screen having at least one pivotal coupling member on one lateral thereof. The rotary shaft is coupled to the pivotal coupling member. Thereby, the driving recorder screen is integrated with the rearview mirror baseplate. Thus, the driver can watch the mirror and the driving recorder screen simultaneously, neither distracted nor fatigued. Therefore, the present invention not only can increase convenience of drivers but also can improve safety of driving.
