Abstract: Provided are a composite plastic floor and a preparation method thereof. The composite plastic floor includes a first substrate layer, a cork layer, a second substrate layer, a wear-resistant layer, and a coating that are laminated in sequence; where the cork layer has a thickness greater than that of the first substrate layer and the second substrate layer, and the cork layer has a density of 0.18 g/cm3 to 0.3 g/cm3; and the first substrate layer and the second substrate layer independently include 20 wt % to 50 wt % of polyvinyl chloride (PVC) and 50 wt % to 80 wt % of a stone powder.

Abstract: A mobile device can wirelessly connect, using transceivers, to a medical item and a wristband worn by a user. The mobile device includes a software application enabling a user to input distance thresholds. The wristband can also include a software application enabling a user to input distance thresholds. Both the mobile device application and the wristband application can monitor signals between the medical item and wristband. In another system, a medical item distance alert system can include a plurality of medical items. In another system, a mobile device is not in communication with the wristband or medical items. The wristband software application can monitor signals between medical items and provide alerts in the absence of another mobile device. Preferably, ultra-wideband (UWB) and Bluetooth transceivers can be implemented to provide accurate distance estimates with low power usage.

Abstract: A suture passer guide that includes an elongate member having a longitudinal axis and defining a first proximal opening and a first distal opening. The first proximal and distal openings are substantially aligned with one another such that a suture passer can be extended through the first proximal and distal openings at an acute angle relative to the longitudinal axis of the elongate member. The suture passer guide can be configured to be passed through a central lumen of an endoscopic port.

Abstract: A media diary application implemented in an electronic device, such as a digital communication device that provides for a topographic presentation or view of the quantity of media files associated with specific time periods. In addition, the topographic view provides the capability to distinguish between different media files based on a chosen media file characteristic. In the topographic presentation the quantity of media files are represented graphically, typically in a line graph or bar graph type presentation. As such, the topographic view of the media diary application provides the user of the diary an efficient means of locating media files and assessing quantity of media files in relation to time span.

Abstract: A block includes a hole provided on one side of the block, two fifths of the length of the block from one end, and a pin provided on the opposite side of the block two fifths of the length of the block from the other end. The hole is arranged to be connected to the pin of a like underlying or overlying block, so that a plurality of said blocks can be connected to form a double helix. Each end of the block includes a knob for connecting a plurality of blocks to a flexible member which follows a double helix shape to produce a model for DNA.
