The invention provides a foot stand with the lamp effect. The foot stand comprises a foot stand main body, a light source, a fixed bracket and a controller. The light source is arranged on the foot stand main body or the fixed bracket. The foot stand can directly emit light to form the lamp effect or is further provided with a light guide medium for the light source to irradiate the light guide medium to generate different lamp effects. Meanwhile, the on-off, the brightness and the color changes of the light source are controlled by the controller, so that various static or dynamic lamp effects can be achieved under the condition that the normal function of the foot stand is not influenced.

The invention discloses an infrared position sensing device, and the device comprises a thermopile sensing element and a signal processor. The thermopile sensing element senses the infrared light emitted in a sensing range, and outputs a corresponding first sensing signal. The signal processor is electrically connected with the thermopile sensing element, and processes the first sensing signal, soas to obtain a background sensing value and a current sensing value. The signal processor judges whether the difference between the current sensing value and the background sensing value is greater than a first critical value or not, so as to determine whether there is a target object in the sensing range, and output a corresponding first control signal. The device still can recognize whether a human body is in the sensing range or not under the condition that human body is stationary.

The invention provides a method for assisting a dispatching company to assess the working stability of a dispatched person. The method is characterized in that a biographical questionnaire is provided by a server and downloaded into electronic equipment by utilizing a network by the electronic equipment, wherein a plurality of questions are written in the biographical questionnaire, each question provides at least two options for the dispatched person to answer, and then the dispatched person answers the questions in the biographical questionnaire; after the dispatched person fills all the questions, the biographical questionnaire is uploaded into the server by the electronic equipment by utilizing the network, and the server gives a score to each answer to the question of the dispatched person, wherein different answers can have corresponding different scores; and after the scores corresponding to all the questions are accumulated by the server, a total score is calculated by the server, and a working stability value of the dispatched person related to the total score is also calculated.

A ball grid array package structure, it sets multiple bumps in a ball grid array (BGA) substrate, and when making surface mount technology (SMT), it has more a supporting role to avoid the package structure bursting apart due to external force pressure, and also when the users use this semiconductor packaging module, the package structure can avoid damaging due to external force pressure.

Disclosed in the invention is a negative voltage detection apparatus. The apparatus is characterized in that a sampling circuit is electrically connected to a positive voltage ground terminal and a negative voltage ground terminal; and thus a voltage drop is generated based on a voltage difference of the two ground terminals and a sampling current is generated. A current transformer is electrically connected to the sampling circuit and a negative pressure reference node, so that the sampling current is outputted relatively and conveniently when the voltage drop is generated. A first voltage-dividing sampling resistor is electrically connected to a positive voltage reference node and a connecting node and a second voltage-dividing sampling resistor is electrically connected to the negative voltage reference node and the connecting node; and the resistance values of the first voltage-dividing sampling resistor and the second voltage-dividing sampling resistor are equal. When the sampling current outputted by the current transformer passes through the second voltage-dividing sampling resistor and then a negative sensing voltage is generated at the connecting node. Therefore, the precise negative sensing voltage can be detected effectively and the negative sensing current or power of the voltage can be obtained.
