Systems and methodologies are provided for improving dynamics of striking a key on a keypad during operation thereof, by shifting contours (e.g., slope of a key's surface plane) on surface of a key, based on location of that key on the keypad, and a manner (e.g., the finger used) the key is being stroked. Accordingly, the subject invention can employ varying surface contours to optimize contact between a user's finger and the key at any point depending on predetermined geometric locus for the movement of a user's hand and / or fingers when employing the keypad. A wave key and a pillowed key arrangement are disclosed according to exemplary aspects of the invention. Moreover, a raised protrusion (“ski jump feature”) can be provided around edges of keypad to enhance grip capabilities for the key pad and / or the host device.

A mobility assistance device is disclosed including a main shaft having a handle attached to one end thereof and a ground engaging member attached to an opposite end. The ground engaging member includes a support member and at least one generally arcuate-shaped foot depending therefrom adapted to contact a supporting surface that facilitates a maximization of a traction and a surface to surface contact between the arcuate-shaped foot and the supporting surface. The shaft and the handle are oriented in respect of the ground engaging member to facilitate a proper posture and a gait of a user, thereby maximizing a stability of the user.

The invention relates to the field of heat exchange, and discloses a novel micro-flow plate. The micro-flow plate is formed by compounding two plate pieces and comprises an inner side medium flow channel and two outer side heat exchange surfaces; the inner side medium flow channel is composed of a distribution channel, a collecting channel and net-shaped crossed micro heat exchange channels; a first medium enters the micro-flow plate and is distributed by the distribution channel and then enters the net-shaped crossed micro heat exchange channels to be sufficiently turbulent, heat is exchangedbetween the two outer side heat exchange surfaces and the second medium on the outer side of the micro-through plate when flowing through the micro heat exchange channels; a heat conduction componentused for increasing the heat exchange area of the second medium is arranged on the outer side heat exchange surface of at least one of the two plate pieces. The micro heat exchange channels are uniformly distributed in the whole novel micro-through plates in a net-shaped staggered mode and ensures that the first medium fully utilizes the heat exchange surface; further, a heat conduction part is arranged on the outer side heat exchange surface of at least one plate piece, the heat exchange area of the second medium is increased through the arrangement of the heat conduction component, and themaximization of the heat exchange effect is facilitated.

A motor starter module is provided, the module according to the present disclosure including a PCB (Printed Circuit Board) substrate configured to communicate with and control the magnetic contactor, a mechanism part operating in association with an operation of the magnetic contactor, and an upper case covering the PCB substrate and an outer case of the mechanism part, whereby the magnetic contactor can be locally and directly driven, and controlled via communication to reduce a line cost, to shorten an operation time and to promote maximization of spatial utilization.

The invention relates to the field of heat exchange, in particular to water, oil, CO 2 A device for heat exchange between similar or non-homogeneous media such as air, refrigerant, etc. The micro-pass plate is composed of an inner medium flow channel and two outer heat exchange surfaces. The inner medium flow channel is composed of a distribution channel, a collection channel and a network of intersecting micro heat exchange channels. The inlet end of the micro heat exchange channel is connected with the distribution channel, and the outlet end is connected with the collection channel. The micro-pass plate is compositely formed by two plates, and the periphery of the two plates and the raised joint in the middle are tightly combined to form a whole. The network-shaped interlaced micro-channels and numerous recombination points evenly distributed on the entire plate surface make the medium in the flow channel form turbulent and swirling flow, and exchange heat with the outside through the thin plate quickly and efficiently. The micro-pass plate has many advantages such as ultra-thin, good mass production processability, high heat exchange efficiency, small volume, and low cost.

The invention discloses a ferroferric oxide nano-composite particle and a preparation method and applications thereof. The composite particle is a ferroferric oxide nano-composite particle with the particle size of 10-30nm, and 1,4-dihydroxy anthraquinone and fluorenylmethoxycarbonyl are modified on the surface of the ferroferric oxide nano-composite particle. The preparation method comprises the steps of: firstly, carrying out a hydrothermal method on ferric trichloride hexahydrate, sodium acetate, 1,6-hexanediamine and ethanediol to obtain the ferroferric oxide nano-composite particle, then producing 1,4-dihydroxy anthraquinone, chloroacetyl chloride, and N,N-dimethylformamide into dyes, then adding the ferroferric oxide nano-composite particle, sodium carbonate and the dyes into acetonitrile to carry out a reflux reaction, carrying out solid-liquid separation, washing and drying on the obtained reaction liquor to obtain an intermediate product, then dispersing the intermediate product into the N,N-dimethylformamide, adding dispersion liquid into the fluorenylmethoxycarbonyl, stirring for 2 hours, and carrying out solid-liquid separation, washing and drying to obtain a target product. The ferroferric oxide nano-composite particle can be used for fast detecting four heavy metal ions, namely copper, zinc, cadmium and mercury in an aqueous solution.
