摘要： A roaster for roasting coffee beans includes a roasting chamber having a top and a bottom for holding coffee beans when the beans are being roasted, a cover seated on the top of the roasting chamber and a base on which the bottom of the roasting chamber is seated. A device is provided in the base for supplying airflow into the roasting chamber. A controller controls the airflow supplying device to generate a roasting temperature inside the roasting chamber that tracks a predetermined temperature curve. The temperature curve includes a first stage in which the roasting temperature is set to a first predetermined level for a first predetermined time period, and a second stage in which the roasting temperature is set to a second predetermined level that is higher than the first predetermined level. The second stage includes a plurality of stages including a current stage in which the roasting temperature is set to a current predetermined level for a current predetermined time period and a subsequent stage in which the roasting temperature is set to a subsequent predetermined level that is higher than the current predetermined level for a subsequent predetermined time period.

摘要： A frequency stability analysis and design method for frequency robust resonators, such as MEMS resonators, is presented. The frequency characteristics of a laterally vibrating resonator are analyzed. With the fabrication error on the sidewall of the structure being considered, the first and second order frequency sensitivities to the fabrication error are derived. A relationship between the proof mass area and perimeter, and the beam width, is developed for single material structures, which expresses that the proof mass perimeter times the beam width should equal six times the area of the proof mass. Design examples are given for the single material and multi-layer structures. The results and principles presented in the paper can be used to analyze and design other MEMS resonators.

摘要： Process management techniques using a representation state transfer architecture include, for example, a method of managing a given process in a data-centric manner in a client/server environment, comprising at least one client and at least one server. In an exemplary method, the server obtains from the client at least one request associated with the given process. In response to the request obtained from the client, the server generates an entity, wherein the generated entity is represented in terms of a data model and a lifecycle model associated therewith, wherein the lifecycle model comprises states and state transitions with each transition caused by one or more activities in the given process, and wherein the given process is represented as a collection of communicating entities. The server sends a response to the at least one request to the client, wherein the response is based at least in part on the generated entity.

摘要： Voltage controlled oscillator (VCO) has been widely used in radio frequency communication systems. In a typical VCO implementation, a pair of directly cross-coupled MOS transistors is used as a switching device and an LC resonant circuit is used to tune the desired frequency. The direct cross coupling of the MOS transistor pair will result in limited output voltage swing since a large swing may cause the MOS transistors into a linear region to increase phase noise. The VCO system to increase the output voltage swing according to one embodiment of the present invention includes DC-blocking capacitors to avoid direct cross coupling of the MOS pair. The VCO further includes circuit to provide bias for the gate voltage of the MOS pair. A method for increasing the output voltage swing is disclosed for a VCO system having LC resonant circuit. The method includes providing DC-blocked cross coupling from the drains of the cross-coupled transistor pair to the gates of the cross-coupled transistor pair. The method also includes providing an offset voltage to the gates of the cross-coupled transistor pair to reduce the maximum gate-to-drain voltage of a cross-coupled NMOS transistor pair or maximum drain-to-gate voltage of a cross-coupled PMOS transistor pair so that the cross-coupled transistor pair will work in a saturation region when the output voltage swing is increased.

摘要翻译： 压控振荡器（VCO）已广泛应用于射频通信系统。 在典型的VCO实现中，使用一对直接交叉耦合的MOS晶体管作为开关器件，并且使用LC谐振电路来调谐期望的频率。 MOS晶体管对的直接交叉耦合将导致有限的输出电压摆幅，因为大的摆幅可能导致MOS晶体管进入线性区域以增加相位噪声。 根据本发明的一个实施例的用于增加输出电压摆幅的VCO系统包括隔直电容器以避免MOS对的直接交叉耦合。 VCO还包括为MOS对的栅极电压提供偏置的电路。 对于具有LC谐振电路的VCO系统，公开了一种用于增加输出电压摆幅的方法。 该方法包括从交叉耦合晶体管对的漏极到交叉耦合晶体管对的栅极提供DC阻塞的交叉耦合。 该方法还包括向交叉耦合晶体管对的栅极提供偏移电压以减小交叉耦合NMOS晶体管对的最大栅极至漏极电压或交叉耦合PMOS的最大漏极 - 栅极电压 晶体管对，使得当输出电压摆幅增加时，交叉耦合晶体管对将在饱和区域中工作。

摘要： Laser power monitoring arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards. An auxiliary light detector independently monitors the output power of a laser beam, and directly receives a portion of the laser beam reflected from a diffractive optical lens surface of an optical assembly for optically modifying the laser beam, or from a coated or uncoated inclined surface of a split collimating lens of the optical assembly. The split collimating lens may have its lens portions in mutual contact or separated by an air gap.
