Abstract: The present disclosure provides a method for group number-based microblog aggregation and a system for group number-based microblog aggregation, which are used for realizing microblog aggregation display for group numbers. In the present disclosure, the binding relationship between a group number and microblog accounts is established, a large number of microblog accounts are bound by one group number, so that a client can initiate a microblog aggregation request based on the group number, and microblog messages issued by a large number of bound microblog accounts can be obtained by only transmitting one group number in an inquiry interface. According to the present disclosure, group users can learn the microblog dynamic states of other group users in real time conveniently, group functions are expanded, and time and network traffic of the users are saved.

Abstract: For each phase of a controller, a pair of semiconductor switches comprises a high side switch and a low side switch. A direct current voltage bus provides electrical energy to the semiconductor switches at a test voltage level less than a full operational voltage level. A measuring circuit is adapted to measure the direct current bus voltage. A data processor determines that a deficiency in a tested, related semiconductor switch is present if the measured direct current bus voltage decreases or collapses upon activation of a particular semiconductor switch in the same phase of the controller, or if other sequential test results indicate a deficiency. If the deficiency in the related semiconductor switch is present the processor may prevent the voltage supply from providing the full operational voltage to the direct current data bus to prevent damage to the motor or the controller, for example.

Abstract: At least one example embodiment discloses a method of estimating a position of a rotor in a motor. The method includes determining a first estimated position of the rotor using a first algorithm, determining a second estimated position of the rotor using a second algorithm, the second algorithm being different than the first algorithm, determining a first error based on the first estimated position and the second estimated position, and determining a third estimated position of the rotor based on the first error.

Abstract: At least one example embodiment discloses a drive system including a motor including a rotor, the motor configured to receive a measured current, a controller configured to generate a voltage command for the motor, a sliding mode observer configured to determine an estimated current for the motor based on the voltage command, determine a difference between the measured current and the estimated current, and determine a switching control vector and an estimator configured to estimate a rotor position based on the switching control vector, the switching control vector being determined based on the difference and adaptive parameters of the sliding mode observer, the controller being further configured to control the motor based at least in part on the estimated rotor position.

Abstract: A mounting apparatus for a data storage device includes a chassis (10), a data storage device (50) with a groove (522) defined in a sidewall (52) thereof, a supporting bracket (20) fixed to the chassis (10), the supporting bracket (20) having a sidewall (22) defining a through hole (221) and a recess (228) therein and a positioning member (30) adapted to be pivotably mounted to the supporting bracket (20). The positioning member (30) has a protrusion (361) engaging in the recess (228) for locating the positioning member (30) and a locating pin (341) extending through the through hole (221) of the supporting bracket (20) to engage in the groove (522) of the data storage device (50) for securing the data storage device (50) on the chassis (10).

Abstract: A storage device assembly includes a storage device (50) with a fastener (524) thereon, a bracket (10) for accommodating the storage device and an operating member (40) slidably attached to the bracket. The bracket defines a guiding hole (166) for the fastener of the storage device inserting therethrough. The operating member includes a latching portion (426) and a deflectable mounting portion (46). The operating member has a locked position in which the latching portion engages with the fastener, and a unlocked position in which the mounting portion is biased to disengage the latching portion from the fastener.

Abstract: A mounting apparatus for a data storage device includes a chassis (10), a data storage device (70) with a groove defined in a sidewall thereof, a supporting bracket (20) fixed to the chassis (10), an elastic tab (25) mounted to the supporting bracket (20), a connecting rod (30) movably attached to the supporting bracket (20) and a poke rod (40) pivotably mounted to the supporting bracket (20) and movably connected with the connecting rod (40). The supporting bracket (20) has a sidewall (22) with a rectangular hole (226) defined therein. The elastic tab (25) has a protrusion (256) extending through the rectangular hole (226) for engaging in the groove. The connecting rod (30) has a post (332) for urging the elastic tab (25) to move outwards. That the connecting rod (30) is pushed urges the data storage device (70) to retreat from the supporting bracket (20).

Abstract: A mounting apparatus for securing a storage device (50) with a mounting hole (522) defined therein includes a bracket (20) for receiving the storage device, an operating member (40), a fastening member (30) and a resilient member (60) compressed by the fastening member. A through opening (248) is defined in the bracket. The operating member movably engages with the bracket includes a pressing portion. The fastening member pivotably attaches to the bracket includes a locking portion. The locking portion extends through the through opening of the bracket and engages in the mounting hole of the storage device under the pressure of the pressing portion of the operating member. When the operating member is pulled off, the resilient member rebounds to rotate the locking portion, thereby disengaging the locking portion from the mounting hole of the storage device.

Abstract: A mounting apparatus for securing a storage device (70) with a mounting slot (72) defined therein includes a bracket (30) for accommodating the storage device and a mounting member (50) pivotally attached to the bracket. A through opening (41) is defined in the bracket. A locating clip (46) extends from the bracket. A positioning block (59) protrudes from the mounting member corresponding to the through opening of the bracket. A latching finger (62) is formed at the mounting member for engaging with the locating clip. When the mounting member is rotated to engage the latching finger with the locating clip of the bracket, the positioning block inserts through the through opening of the bracket and engages in the mounting slot of the storage device.
