Abstract: A pair of glasses is provided, including a frame and at least one first magnetic member. The frame includes an inner surface and an outer surface opposite to each other, and the inner surface has at least one first receiving groove disposed thereon and includes at least one projection located within the at least one first receiving groove. The at least one first magnetic member is configured to be attached with at least one second magnetic member by a magnetic attractive force. The at least one first magnetic member includes at least one recession disposed thereon. The at least one first magnetic member is received within the at least one first receiving groove and the at least one projection is received within the at least one recession.

Abstract: A utility knife assembly includes a case having a slot in which two blades are received. A resilient plate is secured in the slot and includes two resilient fingers to push the blades out from the slot. A switch unit is connected to the case and selectively activates either one of the two blades to be pivoted out from the slot.

Abstract: The disclosure proposes a method of power allocation and a base station using the method. The method is applicable to a base station for transmitting information signals to at least two user equipments in a non-orthogonal multiple access (NOMA) system. The method includes: setting a first transmit power of a first user equipment to be smaller than a second transmit power of a second user equipment, where a channel gain of the first user equipment is larger than that of the second user equipment; calculating a first system capacity of the first user equipment according to the first transmit power, and calculating a second system capacity of the second user equipment according to the second transmit power; summing the first system capacity and the second system capacity to obtain a sum capacity; and calculating the first transmit power and the second transmit power based on maximizing the sum capacity.

Abstract: A handy riveter device includes a fastening screw, a casing, a handlebar and a pulling member. The casing has a left cover and a right cover connecting to each other. The casing has a receiving space, an attaching face and a top face. A hole is opened on the casing and communicating with the receiving space. The pulling member is slidably assembled into the receiving space. The pulling member has an engaging groove and a resisting block. An elastomer abuts against the pulling member and the receiving space. The handlebar is assembled into the casing partially and a pivoting rod passes through the casing and the handlebar. Under this arrangement, a user assembles the fastening screw into an articles and the handle bar and sets the handy riveter device on the articles and pushes the handlebar to fasten the articles via the fastening screw.

Abstract: A revolving screwdriver with ratchet structure includes a handle, a pushing rod, and a sliding member. The sliding member has a receiving space and a holding chamber defined therein. A revolving cylinder is received in the holding chamber. The receiving space receives at least one ratchet wheel, two rotators, a limiting member, a base, and an adjuster. The at least one ratchet wheel engages with a driving shaft. The rotators selectively engage with the at least one ratchet wheel. The limiting member locates between the rotators and has a protrusion formed thereon. A base has a first guiding slot defined therein. The adjuster has a driving hole defined therein. The protrusion passes through the first guiding slot and the driving hole for being driven by the adjuster and moving along the first guiding slot.
