A drop test device for testing any deviation between the gravity line of an object and a defined vertical orientation includes a dropping machine and a drop panel installed on the dropping machine. The drop panel includes a support board, a plurality of restriction boards fixed on the support board, a plurality of rollers mounted on the support board and a sliding board positioned on the plurality of rollers for supporting the object. The sliding board is positioned between the plurality of restriction boards and slides on the plurality of rollers. If the gravity line of the object is not on the same line as a supportive strength line of the object, the sliding board moves on the support board and triggers the plurality of restriction boards.

A computer enclosure includes a computer case and a power supply tray. The computer case includes a side plate and a rear plate adjacent to the side plate. A clamping portion is located on the rear plate, and an opening is defined between the side plate and the rear plate. The power supply tray is attached to the opening and includes a clipping member. The clipping member includes a securing portion extending from the power supply tray and a clipping portion rotatably attached to the securing portion. The clipping portion is engaged with the clamping portion to secure the power supply tray to the computer case, and the clipping portion is rotatable relative to the rear plate to disengage the clipping portion from the clamping portion.

A test support apparatus includes a base, a support bracket, a first positioning member mounted to the support bracket; and a positioning arm. The support bracket is pivotally mounted to the base and keeps an angle relative to the base. The support bracket supports a product. The positioning arm defines an elongated positioning slot. The positioning arm is mounted to the base. The first positioning member is positioned in different positions of the elongated positioning slot to change the angle.

The present invention relates to compounds, compositions, and methods for the study, diagnosis, and treatment of traits, diseases and conditions that respond to the modulation of IDH1 and mutant IDH1 gene expression and/or activity, and/or modulate an IDH1 or mutant IDH1 gene expression pathway. Specifically, the invention relates to double-stranded nucleic acid molecules, including small nucleic acid molecules such as short interfering nucleic acid (siNA), short interfering RNA (siRNA), double-stranded RNA (dsRNA), micro-RNA (miRNA), and short hairpin RNA (shRNA) molecules, that are capable of mediating or that mediate RNA interference (RNAi) against IDH1 or mutant IDH1 gene expression.

A clipping apparatus includes a base, a support bracket, a positioning member and a rotating arm. The support bracket is located on the base. The support bracket is oblique relative to the base and defines a sliding slot. The positioning member is slidably engaged in the sliding slot. A first end of the rotating arm is pivotably engaged with the base. A second end of the rotating arm, opposite to the first end, is secured to the positioning member. An angle defined between the base and the support bracket is adjustable when the positioning member is slid relative to the base.

A surgical instrument comprising a handle portion, an elongated body portion extending distally from the handle portion, and a tool adjacent the distal portion of the elongated body portion and having at least one jaw movable to a clamping position to clamp tissue. A tactile feedback system includes an expandable member extending from the handle portion, the expandable member providing a tactile indicator of a tissue parameter of tissue clamped by the least one jaw.
摘要:
A system and method including an elongate member having a proximal end and a distal end, the elongate member defining a longitudinal axis and configured to rotate relative to the longitudinal axis is presented. The instrument further includes a handle member configured to be attached to the proximal end of the elongate member, the handle member operatively associated with a rotation mechanism. The instrument also includes an end effector configured to be attached to the distal end of the elongate member, the end effector operatively associated with an articulation mechanism and configured to be pivotable throughout a plurality of directions relative to the longitudinal axis of the elongate member. A software algorithm is used to identify, track, and control directional movement of the end effector in accordance with rotational movement of the elongate member.

A surgical instrument including an integrated wireless camera includes a handle assembly housing control circuitry. An elongated shaft extends from the handle assembly and includes an end effector disposed at a distal end thereof. An image sensor assembly is disposed toward the distal end of the elongated shaft and is electrically coupled to the control circuitry. The image sensor assembly is configured to convert an optical image into an electrical signal and communicate the electrical signal to the control circuitry. The control circuitry is configured to process the signal and wirelessly transmit the processed signal to a wireless receiver positioned remote of the surgical instrument.
摘要:
A blend of one or more crosslinked polymers or copolymers prepared from an olefinically unsaturated polymerizable carboxylic or anhydride monomer and at least one high molecular weight essentially linear polymer prepared from an olefinically unsaturated polymerizable carboxylic acid monomer. The blend is neutralized to typically a low pH, and generally contains a noncovalent, e.g. ionic, crosslinking agent, and a cure rate modifier. The hydrogel blend is capable of containing a large amount of water, has good tack, good adhesion, and can be utilized as an application vehicle having a backing thereon as well as containing various substances such as personal care compounds, pharmaceuticals, active ingredients, and the like.
