Field Guide

Can you help me find a poem by Robert Hass, author of “Field Guide” etc.?

I heard Hass read this poem years ago and never found it in one of his collections, but maybe someone else knows it, has a copy, or can direct me to it online. It is a simple observation, the poet admiring a young couple with a baby at a sidewalk cafe. The voice in the poem is moved by the hopefulness of this family, of this passing moment when ‘all things are possible.’ Does anyone out there know this poem’s title? Collection?

could be this is what you are looking for,
“The Addison Street Anthology: The Berkeley Poetry Walk”
By ed. Robert Hass, Jessica Fisher, its a poetry book

This anthology celebrates the rich tradition of Berkeley’s literary ad artistic history. A street in the downtown Arts district was designated as the site for panels embedded in the sidewalk introducing passerbys to the work and the writers who have called Berkeley home for a time. The collection is edited by Robert Hass, former Poet Laureat.

Function of over dischargeonce voltage of any battery in the group gets lower than the over charge protection point, discharge cuts off to ensure all batteries work beyond the over charge protection point. Function of over currentduring the discharge process of battery group, once discharge current gets over the set over current protection point, output cuts off to ensure battery group works within the safe limit of current. Function of short circuit protectiononce battery groups output port appears the condition of short circuit, it cuts off to ensure battery group not to be damaged because of short circuit. Function of voltage balancingin the late charging period of battery group, voltage difference that appears during the using process of each battery could get balancing revised to ensure battery groups capacitance.Specified TypesYS80302 Technical Index Item 12 seriesbalancing guard shieldOvercharge protection (V)3.95??0.025 Overcharge recovery (V)3.80??0.05 Overdischarge voltage (V)2.2??0.1 Overdischarge recovery (V)Cutload or chargeNormalworking current (A)30Overcurrent protection (A)60Internalresistance ??(??m/ohm)<30Chargingbalancing current (mA)60Chargingbalancing voltage (V)3.63??0.03 Overcharge postpone time (mS)1.2Overdischarge postpone time (mS)144Temperatureprotection ( )65 (option)Temperaturecharacteristic??1.0mv/Workingtemperature????????( )-10~+60Storagetemperature??????????( )-30~+85Powerloss (uA)<400 (Vn=3.2v normal)<200 (Vn2.2v??Under-voltage) Dimensions (mm)120 x 60 x 9Weight(gram)78 Download Installation guide here.Usage and Attention After purchasing the protection mould, users should connect lines in compliance with the instruction. Voltage usually exists in the battery, so operators should peel one line and then connect another starting from B-. Lines should be connected from the low position to the high position with no mistake of order, or the irreparable damage could be caused. When lines get connected, bits of copper and tin should not cling to the guard shield. Protection board should be connected to battery group with compliance to specifications and any leading line should not be put on the back of the board but on the lateral side. When equipping the guard shield, hard epoxy sheer should be fixed on the back of the board as the barrier to prevent the squeezing against short circuit. When welding
