Abstract: An electronic apparatus with a two-way cable connection construction is provided. The electronic apparatus includes a casing kit and an electronic device. The casing kit includes a casing, a main circuit board and an auxiliary circuit board. The main circuit board and the auxiliary circuit board are disposed inside the casing. The auxiliary circuit board and the main circuit board are electrically connected to each other and non-coplanar with each other. When the electronic device is inserted into a mounting slot of the casing along a first direction, a mating electrical connector of the electronic device is connected to a first electrical connector of the auxiliary circuit board. When the electronic device is inserted into the mounting slot of the casing along a second direction opposite to the first direction, the mating electrical connector of the electronic device is connected to a second electrical connector of the auxiliary circuit board.

Abstract: A sensor, a time alignment apparatus, a time processing method, and a time alignment method are provided. The sensor begins to sense at least one sensed data at a first local time instant. The sensor transmits a response message at a second local time instant. The response message carries the at least one sensed data, the first local time instant, and the second local time instant. The time alignment apparatus receives the response message at a first global time instant. The time alignment apparatus calculates a second global time instant that the at least one sensed data being sensed according to a required transmission time between the time alignment apparatus and the sensing apparatus, a clock skew rate between the time alignment apparatus and the sensing apparatus, the first global time instant, the first local time instant, and the second local time instant.

Abstract: A candidate key retrieving apparatus, a candidate key retrieving method and a tangible machine-readable medium thereof are provided. The candidate key retrieving apparatus comprises a storage unit and a microprocessor. The storage unit is configured to store a table recording a data amount of the table, a plurality of attributes, and a data distinct amount and a data type of each attribute. The microprocessor is configured to generate a candidate key according to the data amount, the distinct amounts and the data types.
