  • Publication number: 20240093298
    Abstract: Systems, methods, and apparatuses are provided for diagnosing auto-immune diseases such as systemic lupus erythematosus (SLE) based on the sizes, methylation levels, and/or genomic characteristics of circulating DNA molecules. Patients provide blood or other tissue samples containing cell-free nucleic molecules for analysis. Massively parallel and/or methylation-aware sequencing can be used to determine the sizes and methylation levels of individual DNA molecules and identify the number of molecules originating from different genomic regions.

  • Publication number: 20150108234
    Abstract: The present invention describes a spraying device comprising: a housing adapted to receive a container of fluid; actuation means configured, in use, for periodic actuation of the container of fluid; motion sensor means; a controller in operable communication with said actuation means and said motion sensor means; wherein the actuation means is operable, in use, to actuate at a time interval of t1; and wherein the motion sensor means is operable, in use, to detect motion in the vicinity of the device and communicate any detection to the controller which causes the actuation means to actuate; and wherein subsequent detection of motion by the motion sensor is communicated to the controller which causes the actuation means to actuate at a time interval of t2; and wherein t2?t1. The present invention further describes a method of spraying fluid from a container.

  • Patent number: 7822723
    Abstract: Provided are a method, system, program, and data structure for controlling access to a sensitive function in a class. A friend object is generated indicating at least one external function from at least one external class external to the class including the sensitive function. A call from a calling function in a class external to the class including the sensitive function is processed and the calling function is permitted access to the sensitive function in response to determining that the friend object indicates that the calling function can access the sensitive function.

  • Patent number: 7089242
    Abstract: Provided are a method, system, and program for controlling access to a sensitive function in a class. A friend object is generated indicating objects from external classes external to the class including the sensitive function. The objects indicated in the friend object are capable of being modified during runtime. A call from an external function in one class external to the class including the sensitive function is processed during runtime. The calling function is permitted access to the sensitive function if the friend object indicates that the calling function can access the sensitive function.

  • Patent number: 5233650
    Abstract: A telephone handset support device comprising a resilient headband provided with earpads for engaging the ears of the use, and a clip detachably attached to one earpad. The clip detachably connects to the headband and a central opening allows sound from the speaker in the telephone earpiece to pass through the connection to the user's ear. The clip includes a pair of spaced resilient gripping arms which extend generally outwardly away from a base of the clip and towards one another to define a region into which the earpiece of a telephone handset can be placed such that the arms grip around that earpiece. A resiliently mounted lever is urged towards the base and bears on the end of the earpiece so as to press this against the base and together with the gripping arms retains the earpiece in the clip.
