Abstract: A head-mounted fixing device includes a head frame, a bracket and a headband. Two side frame portions of the head frame abut against two sides of a user’s head, and a front frame portion of the head frame is located between the two side frame portions and abuts against the user’s forehead. The headband is movably connected to two first adjusting members of the head frame, so the position of the front frame portion on the forehead can be adjusted by adjusting positions of the two first adjusting members on the headband. The bracket abuts against the top of the head. The headband can wrap around and abut against the back of the head. The head frame, the bracket and the headband abut against the head to restrict the head-mounted fixing device from moving relative to the head, so that the head-mounted fixing device may be worn without shaking.

Abstract: A directional backlit display device includes a light source module, a reflective narrow-angle diffuser, a backlit type display panel, an eye tracking device, and a controller. The diffuser includes a shaft and is utilized to reflect and uniformly diffuse the light to provide a uniform directional light beam. The backlit type display device panel is included on the projecting optical path of the uniform directional light beam. The uniform directional light beam illuminates an image displayed on the backlit type display device panel and projects to a projection area. The controller receives an eye position information from the eye tracking device and determines a coordinate. The controller determines a corrective projection area when the coordinate deviates from the projection area, and the drive module rotates the reflective narrow-angle diffuser around an axis of the shaft according to the corrective projection area, so the image projection area moves with the eye.

Abstract: A database-management system provides sargable evaluation for query predicates that compare an “LHS” encrypted database-column operand to an “RHS” expression operand. The system directly compares the two operands if all their attributes match. If the operands are encrypted string-type values differing only in length, the system truncates the RHS or pads it with encrypted blanks and, if a truncation loses meaningful data, evaluates the predicate as never satisfying an equality condition. In all other cases, if all attributes of a plaintext RHS don't match those of the plaintext data encoded into the LHS column, the system attempts to cast the RHS to match the plaintext LHS data. An error condition or data loss at this step allows the system to sargably evaluate the predicate without further analysis, but if the casting is successful and error-free, the system encrypts the resulting RHS and performs a sargable predicate evaluation.
