Abstract: This disclosure is directed to an electric support rod having a driving assembly, an actuating assembly, and a bearing. The driving assembly has a first outer tube and a driving unit in the first outer tube. An internal thread is configured in the first outer tube. The actuating assembly has a second outer tube and a transmission screw rod in the second outer tube. Multiple elastic arms axially are extended from the second outer tube and arranged spacedly around the transmission screw rod. Each elastic arm has an outer thread structure and a hook portion. The second outer tube is inserted in the first outer tube, the internal thread is screwed with the outer thread structure. One end of the transmission screw rod protrudes from the second outer tube to engage the driving unit. The bearing sheathes the transmission screw rod and the hook portion latches the bearing.

Abstract: A cup generally includes a container body and a cap connected on the container body. The cap has a hollow transparent base defining a central through space and an annular channel around the central through space, a plurality of decorative objects located in the annular channel of the hollow transparent base, a sealing ring, and a top plate. The annular channel of the hollow transparent base can be sealed by the top plate and introduced with a liquid. The top plate defines a first annular groove at its undersurface. The sealing ring is disposed in the first annular groove of the top plate to prevent a beverage or drink contained in the container body from leakage. The decorative objects floating on the liquid contained in the hollow transparent base allow the cup to have an attractive appearance and can increase the fun drinking the beverage or drink.

Abstract: According to an embodiment, the projection apparatus maintenance system is adapted for a projection apparatus having a communication interface and a projection unit. The projection unit projects a projection image according to an image data. The method comprises: transmitting a usage data corresponding to the projection apparatus to a mobile apparatus through the communication interface; transmitting the usage data to a network server through the mobile apparatus and receiving a maintenance data which is provided by the network server in correspondence to the transmitted usage data; receiving at least one maintenance command from the mobile apparatus through the communication interface; and executing a maintenance operation corresponding to the projection apparatus according to the at least one maintenance command. As a result, the maintenance efficiency of the projection apparatus can be improved.

Abstract: A method and device for realizing an electric candle flame with a dynamic visual effect. The device comprises a shell, an upper cover, a candle flame simulating object, an LED lamp, a pivot, a candle flame simulating object seat and a water stirring device. The seat is cylindrical and fixed at a center part of the upper cover, and the candle flame simulating object is vertically arranged in the seat in a swinging mode by the aid of the pivot. The LED lamp is arranged on the vertical wall of the seat and located at the lower front of one lateral plane of the candle flame simulating object, and LED lamp upwardly and obliquely emits light to said plane of the candle flame simulating object at an elevation angle. Water is filled in the lower part of the shell with the water stirring device is arranged therein.

Abstract: A cup in this present invention comprises a cup and a lid on top of the cup. The lid has an anti-leaking ring inside of the lid and an annular groove in arc shape used to place a ball inside of the annular groove. A positioning member above the lid has a buffering edge in arc shape at upper portion of the positioning member to block the ball as to prevent ball from lo dropping out of the annular groove. Therefore the ball can be rolled and spun randomly on the lid in order to have more fun while using.

Abstract: A cup generally includes a container body, a lid, a rotatable arm, a straw, and a figurine. The lid is provided with a central hub defining a central through hole. The rotatable arm defines a mounting hole at a first end for fitting over the central hub of the lid. The straw can in inserted into the container body via the central through hole of the central hub. The figurine is fixed at a second end of the arm, so that the figurine together with the arm can be freely rotated around the straw. Thus, the cup can show a unique style and bring more fun to users.

Abstract: The present invention relates to the method for preventing the liquid in the filtering plug-in card form dripping and a plug-in-card type liquid purifying and filtering device. The said liquid purifying and filtering device comprises the water pump, filtering cylinder and filtering plug-in card. In particular, at the top of the said filtering cylinder is equipped with the disassembled filtering plug-in card retainer. When the filtering plug-in card is taken out, such disassembled filtering plug-in card retainer is utilized to place the said filtering plug-in card, thus enabling such filtering plug-in card to leave the liquid level inside the filtering cylinder. In addition, it can set the disassembled top cap retainer for the said filtering cylinder. When the said top cap is disassembled, the disassembled top cap retainer is used to place the said top cap.

Abstract: A method and system for profiling a user based upon a user's previous on-line actions is provided. The profile provides a characterization of the user's preferences based upon a received user event. The user event identifying event identification information and a user identifier. A look-up in a cached web map is performed to retrieve classification information associated with the event identification information. A user profile is retrieved or created for the user identifier. Profile update information is generated based upon the retrieved classification information for the user event, to identify how the user is to be updated based upon the retrieved classification information and defined profiling rules. The user profile is updated and stored for access by an external advertising server. The classification information provides a text-score record comprising a text string and a score defined in relation to a lexical ontology comprising a hierarchy of categories.

Abstract: The present invention relates to a transportation device comprising one riding wheel, a U-shaped frame, and a stepping assembly. The riding wheel is mounted between the two ends of the U-shaped frame and the stepping assembly is mounted on the axle of the riding wheel. The stepping assembly contains a foot pedal and one or two supporting legs with an optional stepping wheel beneath the foot pedal. This device can conveniently convert between a riding mode and a walking mode to allow rider skate, walk, and stand in various ground surfaces.
