Abstract: An electrical card connector (100) for electrically connecting with an electrical card (6) includes an insulator (1) defining a receiving space (14), a number of contacts (2) retained in the insulator, a pair of latching portions (45) and a shield (5) covering the insulator (1). The shield includes a pair of fingers (512) corresponding to the latching portions (45). Each finger defines a cantilever (5121) extending into the receiving space (14) and a latch member (5122) for engaging with the latching portion (45). When a complementary card is inserted into the connector, it abuts against the cantilever (5121) and lifts the latch member (5122) outwardly. The latch member (5122) disengages from the latching portion (45). The card is further inserted in the connector and electrically connects the contacts thereof.

Abstract: A portable storage device (1) includes a memory device with a USB interface (20) and a protective cap (30) detachably mated with the USB interface. The USB interface may be a conventional one, which has a metal shell (21) defined pair of holes (213) therein. The protective cap has a case (31), a spring member (34) mounted therein and a button (33) engaged the spring member. The spring member defines a hook section (343) thereon to engage with the hole of the USB interface. To press said button inwardly disengages the hook section of the spring member from the hole of the USB connector, thereby detaching the USB interface from the cap.

Abstract: A portable storage device (1) includes a memory device with a USB mating port (20) and a protective cap (30) detachably mated with the USB mating port in a mating direction. The USB mating port has an engagement portion (211). The protective cap includes a case (31) for receiving the USB mating port and a latching member (32) on the case. The latching defines a retaining portion (324) thereon to engage with the engagement portion (211) of the USB mating port. The latching member is movable between a disengaged position and an engaged position in the mating direction to thereby engage/disengage the mating port with/from the cap.

Abstract: A portable memory device (1) includes a memory unit, a USB mating port (20) electrically connecting with the memory unit, a protective case (30) detachably mated with the USB mating port and a plastic waterproof member (32) secured in the case. The plastic waterproof member is pressed against a periphery (213) of the USB mating port to seal a gap between the USB mating port and the case. The USB mating port is protected in the case form water penetration. Moreover, the plastic waterproof member imposes a force rising from plastic deformation of the plastic waterproof member on the USB mating port. Therefore, the USB mating port and the case is firmly engaged with each other.

Abstract: The present invention provides novel compositions and methods for lowering blood glucose levels, as well as manufacture processes for producing the compositions. Specifically, the present invention provides novel compositions that are extracts of the plant Prunella Linn and/or Rabdosis (Blume) Hasskarl containing enriched corosolic acid. Methods of isolating corosolic acid at high purity from these plants are also provided. These extracts and the purified corosolic acid can be used for lowering blood sugar levels and reducing accumulation of triglyeride in the treatment of diabetes, obesity and related conditions.

Abstract: Compositions and methods are provided for controlling pests by using cocktails of plant alkaloids. In particular, the pesticidal composition is formulated with water-miscible solvent and comprises two or more plant alkaloids selected from the group consisting of toosendanin, azadirachtin, tomatine, stemonine, nicotine, anabasine, matrine, oxymatrine, sophocarpine, N-oxysophocarpine, cytisine, and aloperine. The water-miscible pesticide can be used to protect crop plants, wood structures and animals from damages by harmful pests, overcome resistance of pests to current commercial pesticides, and reduce contamination to the environment.
