A measuring system (100) includes a measuring instrument (10) and a processing device (20). The measuring instrument includes a base (12), a guide column (14), a sliding member (16), and a digital micrometer (18). The guide column is vertically attached to the base. The sliding member is moveably attached to the guide column. The digital micrometer is firmly fastened to the sliding member. The processing device is electronically connected with the digital micrometer. The processing device receives a measured value from the digital micrometer and diplays a testing result after processing the measured value.

An inventory management system includes a database (40) and a server (30) connected to the database. The database is configured for storing electronic inventory documents associated with information of a raw material. The server includes a loading module (302) and a processing module (304). The loading module is configured for transmitting the electronic inventory documents to the database. The processing module includes a calculating module (3041), an analysis module (3043), and an alert module (3044). The calculating module is configured for calculating a safety stock amount of the raw material. The analysis module is configured for generating an analysis signal indicating whether an on-hand inventory amount of the raw material is balanced, by comparing the on-hand inventory amount with the safety stock amount. The alert module is configured for generating an alert based on the analysis signal. An inventory management method is also provided.

A method is provided herein for determining a remaining useful life of an air filter. The method includes, but is not limited to, measuring a first airflow rate and a first air pressure (P1) in an air cleaner assembly downstream of the air filter, wherein P1 corresponds to the first airflow rate. The method further includes measuring a second airflow rate and a second air pressure (P2) in the air cleaner assembly downstream of the air filter, wherein P2 corresponds to the second airflow rate. The method further includes obtaining pressure differentials A1, A2, B1, and B2 from a data storage device. The method also includes calculating with a processor a result indicative of a useful life remaining for the air filter by taking into account P1, P2, A1, A2, B1, and B2. The method also includes reporting the result to a user.

In accordance with exemplary embodiments, a variable air intake system and method is provided for a vehicle. The system comprises an engine a controller coupled to the engine. The controller also couples to and controls an air intake system including a first air inlet port and a second air inlet port having a valve operable to move between a closed position and an open position responsive to the controller to provide air to the engine via a filter. A sensor is disposed between the filter and the engine to communicate with the controller for controlling the valve. The method comprises determining engine speed and air flow for an engine of a vehicle and comparing via the engine speed and air flow to a respective high threshold and low threshold. A valve within a second (controlled) air inlet port is opened when the engine speed and air flow each exceed the respective high threshold and closed when the engine speed and air flow each are below the respective low threshold.

A radiation reducing apparatus for a wireless communication device includes a sensing module, a control module, and a radiation reducing module. The sensing module senses radiation intensity of the wireless communication device and generates a signal corresponding to the sensed radiation intensity. The control module compares the sensed radiation with a preset radiation intensity threshold. The radiation reducing module is activated by the control module to reduce the radiation of the wireless communication device when the sensed radiation intensity reaches the radiation intensity threshold.

Personal Computer Network (PCN) is a closed network to logically network the global computer users' small network at home through their interfaces and routers. The network architecture contains Local Operating Systems, Regional Operating Systems and Global Operating Systems distributed globally and identified by country codes and area codes. The business informational servers can also be logically connected to the network. The network has module-designed Operating Systems to provide the centralized services to all kinds of computer users. With the module-designed operating systems, the services, functions and features including unifying different kinds of users, providing universal platform, fixed routing, inner connections, universal platform, file system, recording, sorting, multiple Inboxes and intersection searching systems can be developed for the efficiency, sufficiency, flexibilities and convenience. The incoming data and outgoing data in PCN can be separated. Seven layers of TCP are defined, and the transmission with fixed routing is controlled logically.

An exemplary printed circuit board includes a main body and a fixing component. The main body includes a first signal layer, a grounding layer, a power layer, and a second signal layer, arranged in that order. A through hole is defined on the main body, and includes a latching hole and a connecting hole. The latching hole is defined by and extends through the first signal layer. The connecting hole is defined by and extends from the second signal layer to the grounding layer, and communicates with the latching hole. The fixing component passes through the through hole, and thereby forms a direct connection with a grounding point of an electronic device.

A pressing head structure (100) for testing key durability includes a pressing mechanism (10), a rubber head (40), a connecting mechanism (20) and a balance mechanism (30). The pressing mechanism includes a sliding rod (12) and a first spring (16). The first spring is placed over the sliding rod. The connecting mechanism connects the pressing mechanism and the rubber head. The balance mechanism is rotatably fixed to the connecting mechanism. The balance mechanism engages with the pressing mechanism. When the sliding rod moves down, the first spring and the balance mechanism together supply an unaltered resultant resistance in the moving direction of the sliding rod.
