Abstract: An implant for the repair of bone and cartilage that includes a cell conductive zone that contains biopolymeric fibers and an osteoconductive zone that contains biopolymeric fibers and calcium-containing mineral particles. The biopolymeric fibers from one zone overlap with the fibers in the other zone forming a stable physical and mechanical integration of the two zones, thus conferring in vivo stability to the implant.

Abstract: Disclosed are methods for forming targeted collagen products having an amplified desired characteristic, including the step of adding peptides exhibiting a desired characteristic to collagen to form the targeted collagen product. Further disclosed are methods for forming a targeted collagen product lacking an undesired characteristic, including the step of subtracting peptides exhibiting the undesired characteristic from collagen to form the targeted collagen product. Also disclosed are targeted collagen products formed by the disclosed methods.

Abstract: Disclosed are methods for forming targeted collagen products having an amplified desired characteristic, including the step of adding peptides exhibiting a desired characteristic to collagen to form the targeted collagen product. The adding step is performed so that the collagen is crosslinked to the peptide exhibiting the desired characteristic. Crosslinking of the collagen to the peptide exhibiting the desired characteristic occurs by modification of the peptide to facilitate binding to the collagen. Further disclosed are methods for forming a targeted collagen product lacking an undesired characteristic, including the step of subtracting peptides exhibiting the undesired characteristic from collagen to form the targeted collagen product. Also disclosed are targeted collagen products formed by the disclosed methods.

Abstract: A reacting device of dual path synchronous immunochromatographic platform includes a seat, an upper housing, and a fluid dividing funnel. The seat contains two immunochromatographic carriers. The hollow pipe portion has two sloped structures. A force bearing portion of the fluid dividing funnel can be pressed down, so two fluid exits of the fluid dividing funnel move towards these two sloped structures. The specimen drops and is guided into these two immunochromatographic carriers respectively. A reaction result can be observable. The fluid dividing funnel can divide the specimen into two immunochromatographic carriers evenly. The sloped structure can increase the accuracy of specimen supply. Excess specimen can be scraped off for enhancing the solving accuracy. In addition, it can decrease the possibility of false positive problem.

Abstract: A voice prompting method includes steps of: providing a wearable electronic device, obtaining an image and performing an image processing on the image, detecting and identifying a plurality of objects in the image, classifying and judging danger levels of the objects to generate a judgment result, generating a safety warning message corresponding to each of the objects presently having the danger level higher than a specific danger level according to the judgment result, and transforming the safety warning message into a voice form and prompting with the voice form of the safety warning message. Therefore, it can help a user avoid danger and effectively enhance the safety of walking of the user.

Abstract: A carbonate apatite prepared from natural bone. The carbonate apatite has a protein content of 2000-8000 parts per million and a surface area of 15 to 70 m2/g. Also provided is a method for preparing the carbonate apatite from cancellous bone particles.

Abstract: A circulation member positioning structure for a ball screw includes a nut and a circulation member. The nut has a threaded channel, a socket, and a positioning notch. The socket is provided on a wall of the threaded channel and the positioning notch is provided on a wall of socket. The circulation member has a circulation portion, a circulation track, and a positioning protrusion. The circulation portion is provided in the socket of the nut. The circulation track is distributed over one lateral of the circulation portion and connects with the threaded channel of the nut. The positioning protrusion is provided on an opposite lateral of the circulation portion for being engaged with the positioning notch of the nut. Thereby, the circulation member positioning structure helps to simplify the assembling work of the circulation member and to remain the nut small despite the insertion of the circulation member.

Abstract: A tube expander with positioning structure includes a base, a tube clamp, a positioning device, and an adjusting thread rod. Therein, the base has a body and a neck. The body has a guiding groove and the neck is inserted with a rotating thread rod capable of vertically moving. An expanding cone facing the guiding groove is on one end of the rotating thread rod. The tube clamp having tube bores is slidingly disposed in the guiding groove. The positioning device is on one side of the guiding groove, thereby engaging and positioning the tube clamp and positioning the tube bores under the expanding cone. The adjusting thread rod is pivotally disposed on the body for fastening the tube clamp.

Abstract: A method for preparing carbonate apatite from natural bones. The method includes obtaining cancellous bone particles; treating the bone particles with hot water and an organic solvent; repeating the treating step at least once; drying the bone particles; and heating the bone particles at 500° C. to 620° C. for 10 to 50 hours.

Abstract: A compressed implant composite for repairing mineralized tissue. The compressed implant composite includes a matrix formed of biopolymeric fibers and a plurality of calcium- and/or silicate-based mineral particles dispersed in the matrix. The matrix constitutes 4 to 80% by weight and the mineral particles constitute 20 to 96% by weight of the composite. The composite is free of soluble collagen and is expandable to a volume 2 to 100 times of its compressed volume (e.g., upon absorption of water). Also disclosed are methods of preparing the above-described composite.
