Abstract: Systems, methods, and computer-readable media for determining column ordering of a data storage table for search optimization are described herein. In some examples, a computing system is configured to receive input containing statistics of a plurality of queries. The computing system can then determine a new column order (i.e., layout) based at least in part on the statistics. In some example techniques described herein, the computing system can determine the new column order based at least in part on the hardware components storing the data storage table, storage system parameters, and/or user preference information. Example techniques described herein can apply the new column order to data subsequently added to the data storage table. Example techniques described herein can apply the new column order to existing data in the data storage table.

Abstract: Systems and methods of network packet switching use a table representation of a trie data structure to identify a timestamp (TS) range (or time range) for a received packet based on the packet timestamp (TS). The trie data structure is programmed with a plurality of predetermined time ranges. Each node in the trie data structure corresponds to a TS prefix and is associated with a corresponding predetermined time range. A search engine in the network switch can use the packet TS as a key to traverse the trie data structure and thereby matching the packet TS to a predetermined time range according to a Longest Prefix Match (LPM) process. Provided with the TS ranges of the incoming packets, various applications and logic engines in the network switch can accordingly process the packets, such as determining a new destination IP address and performing channel switch accordingly.

Abstract: Disclosed is a modular housing for drivers used for LED lamps. The housing includes connectors for AC in from a power source, DC out to the lamps, and also has connectors allowing for control lines to be received from a control box. The housing includes an arrangement for creating two opposite stacks of drivers. The fronts of the drivers are cooled by circulating air through the space between the stacks, and heat is also dissipated through the side walls of the housing, which acts as a heat sink. The number and specifications of the drivers in the housing are configured such that every module is able to serve a number of LED lamps.

Abstract: A control device of electronic lock is provided for electrically connecting with a lock device of the electronic lock, so as to be adapted for controlling the operation of the lock device. The control device comprises a base plate, a circuit board, a plurality of illuminants, a plurality of communication resilience members, a lid locked on the base plate, an alignment plate, and a touch panel. The illuminants are arranged corresponding to the communication resilience members respectively. The touch panel is electrically connected with the communication resilience members. When the touch panel is touched, the communication resilience member corresponding to the touched position is electrically communicated with the circuit board, that consequently triggers the corresponding illuminant to emit light. The communication resilience members are guided and aligned through the alignment plate so as to avoid signal interference thereamong.
