  • Publication number: 20250049319
    Abstract: An optical detection system integrating tonometer and autorefractor includes first and second optical modules. The first optical module includes a light source, first and second lens sets, a reflector, a first light-splitter and a sensor. The first lens set and reflector are disposed corresponding to light source. The first light-splitter is disposed corresponding to the reflector, second lens set and sensor. The second optical module includes a second light-splitter and first to third optical elements. The incident light emitted by the light source passes through the first lens, reflected by the reflector, passes through the first light-splitter, reflected by the second light-splitter, passes through the first to third optical elements and emitted to an eye. A sensing light from the eye passes through the third to first optical elements, reflected by the second light-splitter and first light-splitter, passes through the second lens set and emitted to the sensor.

  • Publication number: 20250038073
    Abstract: A package structure and a method for forming the same are provided. The package structure includes a first package structure and a second package structure. The first package structure includes a first device formed over a first substrate. The first device includes a first conductive plug connected to a through substrate via (TSV) structure formed in the first substrate. A buffer layer surrounds the first substrate. A first bonding layer is formed over the first substrate and the buffer layer. The second package structure includes a second device formed over a second substrate. A second bonding layer is formed over the second device. A hybrid bonding structure is between the first package structure and the second package structure by bonding the first bonding layer to the second bonding layer.

  • Patent number: 6514229
    Abstract: A safety syringe with a needle sleeve is provided. The needle sleeve is put around a cap of the syringe with a shoulder portion inside the needle sleeve abutting against a rear flange of the cap, such that the cap, a hub tightly fitted in the cap, and the needle sleeve together form a needle sleeve assembly, which allows the hub to temporarily locate closely before a neck portion of a barrel of the syringe, so that the syringe may be sterilized under high temperature without stress deformation and thermal deformation. When the cap is depressed, the hub and a cannula held thereto are caused to move backward and be stably retained to the neck portion of the barrel in an airtight relation. And when the cap is pulled forward again, it brings the needle sleeve to together separate from the hub to expose the cannula for injection.

  • Patent number: 6432088
    Abstract: A safety syringe with a needle sleeve lock is provided. The needle sleeve lock is put around a cap of the syringe with radially outward projected second stoppers at rear end of the cap located between a shoulder portion and two radially inward projected first stoppers inside the needle sleeve lock, such that the cap, a hub tightly fitted in the cap, and the needle sleeve lock together form a needle sleeve lock assembly, which allows the hub to temporarily locate closely before a neck portion of a barrel of the syringe, so that the syringe may be sterilized under high temperature without stress deformation and thermal deformation. When the cap is turned to separate the second stoppers on the cap from the first shoulder portion and the first stoppers of the needle sleeve lock and then depressed, the hub and a cannula held thereto are caused to move backward and be stably retained to the neck portion of the barrel in an airtight relation.

  • Patent number: 6387079
    Abstract: A safety syringe ensuring stable and airtight connection of a hub to a barrel of the syringe is provided. A rear portion of the hub is tightly fitted in a neck portion at a front end of the barrel, such that the hub is prevented from moving out of the barrel via the neck portion. A first airtight contact line is formed at joint of two shoulder portions separately formed on the hub and the neck portion, and a second airtight contact line is formed at a position within a contact surface between the hub and the neck portion, so that the hub is stably and air-tightly connected to the barrel. A plunger is disposed in the barrel to push medical liquid in the barrel into the hub and a cannula fixed to the hub for injection purpose. An engaging cone having a slit is forward projected from a front end of the plunger to engage into receiving holes formed on the hub when the plunger is fully push forward.
