Title: Staple and thread assembly particularly for use in power-driven staplers for medical suturing
Inventor: SOHN ZE EV
IPC: A61B17/064
Filed: 1995-12-14
Abstract: A staple and thread assembly to be driven into the bone by a power-driven stapler while the thread is attached thereto, the stapler having a head section at its forward end formed with a pointed tip for penetrating the bone when driven into it, and a shank section rearwardly of the head.      The longitudinal axis of the shank section is offset from the axis of the head section and is formed with a pair of transverse holes through which the thread is secured such that the thread exits from the holes. The head section forms a protective shroud shielding the thread when driven with the staple into the bone. The thread is secured to the shank section of they staple at a point closer to the staple tip than the rear end of the staple. The staple is constructed from a metal possessing shape memory characteristics, and deforms from a straight configuration at room temperature, to a curved configuration upon being subject to body heat upon implantation into the body. The suture thread is secured to the shank section and, preferably, a recess is provided to the shank section to protect the thread.

Title: Interactive talking dolls
Inventor: MAK CHI FAI
IPC: A63H3/28
Filed: 1997-12-17
Abstract: A set of interactive toys that perform a sequence of actions in response to one another without external activation other than an initial actuation to begin the sequence of actions. Preferably, each toy has an activation switch and/or a receiver for a wireless signal such as an infrared signal which activates the toy. Upon activation, the toy performs a desired action, such as the enunciation of a speech pattern, and signals another toy to perform a responsive action. Preferably, the toy are capable of performing several different action sequences, such as the enunciation of different conversations, the performance of different movements, etc. Additionally, the toys are programmable by a remote control device. The remote control device either functions as an activation switch, initiating a random or predetermined (yet not user determined) sequence of interactions, or as an interaction selector, such that a desired sequence of actions may be selected.

Patent CA-2226793-A1 (CA)
Inventor: CAMPBELL-SMITH IAIN
IPC: G01F23/296
Filed: 1998-01-13
Abstract: Known means for detecting the presence of fluid at a particular level in a container have some form of detector mounted on the wall of the container at the desired level. In the present invention, the detector has a piezoceramic transducer mounted on the front wall inside a sealed plastic cap. The cap is secured to a metal body clamped about an opening through the wall of the fluid container. The transducer receives short bursts of energy from a generator via a logic unit causing it to resonate, the ringing energy being greater when the transducer is not covered by fluid, because it is less damped. A receiver connected to the transducer via the logic unit provides an output to a comparator, which determines whether the signal is above a predetermined level indicating an absence of fluid.

The nut body 2 comprises a base portion 6, at least two screw portions 9 forming a nut as a whole and having threaded grooves 10 on their inner walls, and spring portions 7 extending from the base portion 6 and connected to the respective screw portions 9, each spring portion 7 resiliently biasing the corresponding screw portion 9 so as to be pressed upward from the base plate 6. The outer surface 11 of each screw portion 9 is tapered to reduce the diameter towards the bolt insertion hole 19 of the cap member 3. Correspondingly, the inner side of the cap member 3 is tapered to reduce the inner diameter thereof.

Title: Improved analyzer throughput featuring through-the-tip analysis
Inventor: FREEMAN DAVIS III
IPC: G01N21/75
Filed: 1998-03-05
Abstract: Apparatus and method for detecting patient sample quality, and/or analytes, in the tip used to aspirate the patient sample liquid and then dispense it onto a slide test element. Spectrophotometric analysis is done on the liquid while still in the tip, by scanning the tip for transmittance in a light-tight enclosure, using NIR and adjacent visible radiation, and detecting the absorbence spectra of the liquid. Thereafter, or prior thereto, the liquid is dispensed onto a dried slide test element for assaying analytes that are not assayed spectrophotometrically, thus enhancing throughput. Much smaller liquid volumes, and no through-the-label detection, are required, compared to doing the scanning of the liquid in a primary patient collection container.
