  • Patent number: 9431406
    Abstract: A semiconductor device and a method of forming the same are provided. At least two separated stacked structures and at least two hard mask patterns respectively on the stacked structures are formed on a substrate. A patterned mask layer is formed on the substrate. The patterned mask layer has an opening which exposes a portion of top surfaces of the hard mask patterns and a portion of the substrate between the stacked structures. The exposed portion of the substrate is removed by using the patterned mask layer and the hard mask patterns as a mask, so as to form a trench in the substrate. An ion implantation process is performed by using the patterned mask layer and the hard mask patterns as a mask, so as to form a doped region in the substrate around the trench.

  • Publication number: 20150376703
    Abstract: The present invention relates to systems and methods for predicting an individuals likely response to a pain medication comprising genotyping genetic variations in an individual to determine the individual's propensity for metabolizing a pain medication and likely response to a medication, and preferably diverse reactions to a medication. In particular, the invention comprises analyzing a biological sample provided by an individual, typically a patient or an individual diagnosed with a particular disorder, determining the individual's likely response to a particular treatment, more specifically a pain medication, and thereafter displaying, or further, recommending a plan of action or inaction. In particular, the present invention provides a grading method and system to profile an individual's response to one or more pain medication.

  • Publication number: 20150320207
    Abstract: A bookcase includes a case made of wood plates or plastic plates. The case is formed with a left side plate and a right side plate, a lower side plate and a rear side plate. The lift and the right side plate respectively have a lower edge provided with a moving perforation, which forms a certain depth by making use of the thickness of the wood plate or the plastic plate of the case, respectively having an upper edge disposed with a lifting handle. Thus, a user can move the case by extending fingers into the moving perforations or lift up the case by the lifting handles and further. Two or more cases can be superposed and combined together by having the lifting handles of the lower case inserted into the moving perforations of the upper case. The bookcase of this invention is original in structure, able to be moved, lifted and superposed.

  • Publication number: 20150196121
    Abstract: A portable bookcase includes a case made of planks or plastic plates. The case is formed with a left side and a right side, an upper side, a lower side, a front side and a rear side. The lift and the right side respectively have a lower edge provided with a moving groove, which forms a certain depth by making use of the thickness of the plank or the plastic plate of the case, respectively having an upper edge disposed with a lifting handle. Thus, a user can move the case by extending fingers into the moving grooves or lift up the case by the lifting handles and further. Two or more cases can be superposed and combined together by having the moving grooves of the upper case joined with the lifting handles of the lower case. The portable bookcase of this invention is original in structure, able to be moved, lifted and superposed.

  • Patent number: 9020071
    Abstract: An Amplitude-Shifted-Keyed (ASK) modulator/transmitter has fall time enhanced by pulsing pull-up and pull-down enhancement switches on for a short period of time after a data transition. The enhancement switches draw energy from a coupling capacitor to more rapidly reduce an amplitude of the carrier wave being output. An input carrier wave is applied to gates of p-channel and n-channel current sources that drive the coupling capacitor. Gates of the n-channel and p-channel enhancement switches also receive the input carrier wave when data is high, but are disabled when data is low. Multiple p-channel and n-channel transistors may be used in parallel for each current source or enhancement switch. Each of the multiple transistors in parallel has a gate that is AND'ed with an index signal. The index signals are programmable and determine how many of the parallel transistors are enabled, thus determining the aggregate current.

  • Patent number: 8711982
    Abstract: An envelope detector receives an input that is an Amplitude-Modulated (AM) or Amplitude-Shift-Keying (ASK) coded signal. Each channel has a sample switch and a diode that charge an internal sampling capacitor. A hold switch connects the internal sampling capacitor to a summing output capacitor or to a post-processing circuit. A reset switch discharges the internal sampling capacitor after each sample. Two or more channels may be time multiplexed to sample alternate cycles of the input, and then their outputs combined by the summing output capacitor or by the post-processing circuit. The diodes may be reversed to detect the negative envelope rather than the positive envelope. Clocks for the switches may be generated from the input, or may be from a separate clock source. Since the sampling window is open for a whole input cycle, the clock source is insensitive to phase error.

  • Patent number: 8621598
    Abstract: An embodiment of the present invention provides a system that enables a user to securely invoke a REST (Representational State Transfer) API (Application Programming Interface) at an application server. A client can establish a secure communication channel with an application server, and can send a request to the application server to invoke the REST API. The client can then receive a security token from an authentication system in response to authenticating the user with the authentication system. Next, the client can receive a nonce and a timestamp from the application server. The client can then determine a security token digest using the security token, the nonce, and the timestamp. Next, the client can resend the request to the application server to invoke the REST API with the security token digest. The application server can invoke the REST API if the security token digest is valid.
