  • Patent number: 11998723
    Abstract: Vented syringes are described herein. A vented syringe includes a syringe body and a plunger body. The syringe body defines a syringe cavity. The plunger body is at least partially disposed within the syringe cavity. The plunger body includes an air intake channel defined within the plunger body. The vented syringe further includes a plunger seal that is sealingly engaged with the syringe cavity to cooperatively define a syringe volume. The vented syringe further includes a one-way valve in fluid communication with the air intake channel and the syringe volume, wherein the one-way valve is configured to prevent fluid flow from the syringe volume to the air intake channel and permit fluid flow from the air intake channel to the syringe volume.

  • Patent number: 11329980
    Abstract: Secure communications are provided between a user computing device and a server computing device. An enrollment request is received from a user computing device that is configured via a distributed client software application and is processed. The enrollment request is usable to enroll the user computing device in a network and includes an encrypted partial initial biometric vector associated with a user. An authentication request is processed that is subsequently received that includes an encrypted partial second biometric vector and that is associated with a user of the user computing device. A comparison of the encrypted partial initial biometric vector and the encrypted partial second biometric vector is performed, and a value representing the comparison is generated and transmitted to the user computing device. The user computing device is authenticated where the value is above a minimum threshold.

  • Patent number: 7397049
    Abstract: A system, method and program product for determining parallelism of an ion beam using a refraction method, are disclosed. One embodiment includes determining a first test position of the ion beam while not exposing the ion beam to an acceleration/deceleration electrical field, determining a second test position of the ion beam while exposing the ion beam to an acceleration/deceleration electrical field, and determining the parallelism of the ion beam based on the first test position and the second test position. The acceleration/deceleration electrical field acts to refract the ion beam between the two positions when the beam is not parallel, hence magnifying any non-parallelism. The amount of refraction, or lateral shift, can be used to determine the amount of non-parallelism of the ion beam. An ion implanter system and adjustments of the ion implanter system based on the parallelism determination are also disclosed.
