    • The present invention relates to a communications system (1) for making multimedia calls. The system comprises two multimedia terminals (10,12) and communication means for making a multimedia call over a shared communications network (20), including a firewall (26) through which the multimedia call must pass, and which restricts certain types of communication. Each terminal (10,12) has a number of logical communication ports for the multimedia call, including at least one dynamically assigned port. In the course of setting up the multimedia call, at least one of the terminals (10,12) is adapted to send a request to the other of the terminals to open up one or more of the dynamic ports in the other terminal. The system includes a proxy server (40) between the terminals (10,12) that acts for each terminal as a proxy for the other terminal during the course of the call. The proxy server (40) has logical communication ports for communication with the terminals including one or more pre-assigned ports. The firewall (26) is configured not to restrict communication between one or both terminals (10,12) and the pre-assigned port(s) of the proxy server (40). The proxy server (40) is configured to receive and forward the request(s) to open up said dynamic port(s) via one of its pre-assigned ports.
    • 本发明涉及一种用于进行多媒体呼叫的通信系统(1)。 该系统包括两个多媒体终端(10,12)和用于通过共享通信网络(20)进行多媒体呼叫的通信装置,包括多媒体呼叫必须通过的防火墙(26),并限制某些类型的通信。 每个终端(10,12)具有用于多媒体呼叫的多个逻辑通信端口,包括至少一个动态分配的端口。 在建立多媒体呼叫的过程中,终端(10,12)中的至少一个适于向另一个终端发送请求以打开另一终端中的一个或多个动态端口。 该系统包括在呼叫过程中在每个终端作为另一终端的代理的终端(10,12)之间的代理服务器(40)。 代理服务器(40)具有用于与包括一个或多个预分配端口的终端进行通信的逻辑通信端口。 防火墙(26)被配置为不限制一个或两个终端(10,12)和代理服务器(40)的预分配端口之间的通信。 代理服务器(40)被配置为通过其预先分配的端口之一接收和转发所述请求以打开所述动态端口。

    • The present invention relates to a communications system (1) for handling communications sessions, for example multimedia calls or voice calls. The communications system (1) comprises a local terminal (10), an external server (40), a proxy interface agent (PIA) (11) between the terminal (10) and a shared network (20). The communication means includes a NAT function (32) through which the communications session must pass. The communications session is carried over the network (20) over one or more logical channels between the terminal (10) and the external server (40), during which the first NAT function (32) applies network address mappings on the terminal's transport addresses (14). The PIA (11) acts on behalf of the terminal (10) in communications with the external server (40), and establishes a logical channel on an outbound connection to the server that serves as a control channel between the PIA (11) and the server (40). The PIA (11) establishes dynamic outbound connections to the server (40), and in response to a request from the server or in response to a request from the PIA itself (11), makes one or more associations between the terminal's transport address(es) (14) and identifiable logical channel(s) between the PIA (11) and the server. These identifiable logical channel(s) are established on one or more of the dynamic outbound connections from the PIA (11) to the server (40).

    • A nozzle chip (3) for ejecting a liquid such as in an electrospray device is built from a substrate chip having grooves (5, 7) on a top surface. A lid (25) is attached to the top surface closing the grooves to form channels one of which has an open outlet end (9). At the outlet end a nozzle is formed at or attached and it has an outlet opening from which the liquid is to be ejected. Alignment recesses (13, 15) are made at edges of the substrate chip and they are accurately positioned in relation to the outlet opening, the alignment recesses allowing an accurate mounting of nozzle chip giving the outlet opening of the nozzle a reproducible position in the device where it is to be used. At the outlet end a recess (17) in the substrate chip can be provided and the nozzle can then be located in the recess to mechanically protect it.

    • A system for controlling a defrost cycle of an evaporator having a sensor module and a control module. The sensor module includes a light source configured to emit light toward the evaporator when activated and to deactivate in response to a lockout signal. The sensor module also includes a light sensor configured to determine an amount of the emitted light reflected by the evaporator and to generate a detected light signal that corresponds to the amount of the emitted light reflected by the evaporator. The control module is configured to receive the detected light signal from the light sensor and to compare the detected light signal to a preset threshold. The control module is also configured to generate a termination signal when the detected light signal is less than the preset threshold and to generate the lockout signal when the detected light signal is greater than the preset threshold.
