Abstract: The present disclosure discloses a neck hanging Light-Emitting Diode (LED) lamp with a timer. The present disclosure takes a neck hanging main body as a carrier in design, and a light source configured to light and an electronic timer configured for a user to time in seconds are respectively arranged at both ends of the neck hanging main body, so that this product can have both effects of lighting and timing, which meets conventional lighting work, and can also meet a requirement of the user for a timing function. Moreover, a sleeve that can be pushed and is provided with a lens is arranged at the light source. Under an operation of manually pushing the sleeve, a focus point of far and near light can be further changed, so as to present different lighting effects.

Abstract: A method for protecting a system from being powered off abnormally during an upgrade, which is applied to a system upgrade of a terminal device, comprises: acquiring a startup offset value of one of the plurality of storage partitions; when the startup offset value is the first offset value, starting the first system image file; acquiring an upgrade file, performing an upgrade operation on the second system image file in the current storage partition by using the acquired upgrade file, and setting the startup offset value as the second offset value when the upgrade is successfully completed; and continuing to perform the upgrade operation on the first system image file, and setting the startup offset value as the first offset value when the upgrade is successfully completed. The terminal device is powered off when upgrade operation is performed so that the system of the terminal device cannot be started normally.

Abstract: The present invention discloses a white LED chip and method of manufacturing the same. The white LED chip includes a flip blue LED chip and a preformed conversion layer for light conversion, the method of manufacturing the white LED chip includes the steps of preparing for a preformed conversion layer for light conversion, setting up at least one cavity on the conversion layer, for receiving a blue LED chip(s), attaching the blue LED chip into the cavity; and cutting the conversion layer into a single white LED chip based on each cavity that received a blue LED chip. The invention not only enhance the luminous efficiency of the white LED chip, but also avoid the pollution to bottom electrode of the LED chip, making easier manufacture and higher binning yield.

Abstract: A hardware-based technique for policing traffic in a network node involves programming a set of algorithm-specific policing primitives that establishes a relationship between condition primitives and action primitives and populating a searchable memory with a set of indexed action primitives. Action primitives are then selected from the searchable memory in response to condition primitives related to a received datagram. Policing actions related to the datagram are performed in response to the action primitive. Because the algorithm-specific policing primitives are programmable, a network node can be adapted to implement a wide variety of policing algorithms. Additionally, multiple different policing algorithms can be implemented in hardware without the need for a different set of combinational logic for each different policing algorithm.
